The device is only thin on the edges. The back is almost as thick as the 2011 one. Even then, it has a GTX 680 MX video card which is brilliant. Did anyone want a desktop one? Did they expect one in the 2011 form factor? Is it even possible? And we don't know for sure if it has heating issues. The thin edges make it look sleek, and is still as powerful as one would want in an all in one,
27 inch still has removable ram slots, and we don't know yet for sure if the hard drive can or cannot be upgraded. Only 21 inch users can whine for that.
And why the complaints of the 21 inch version using a 5400 rpm drive? Isn't there a 128Gb SSD which stores the apps and the OS? What noticeable disadvantage would a 5400 rpm drive make?
And the lack of cd drive is a disadvantage for the minority. Seriously, for most people, CDs are used very unoften. So a cheap external one can do it when needed. And for those who use it a lot, it's a disadvantage. But still for a minority. And I chonestly can't think of a disadvantage of a cheap third party CD drive on a desktop. No one has to lug it around. It's only pulled out of the draw when needed.
I still think its a marvellous machine and an absolute beauty.
As someone who does not yet want to give up the optical drive, I feel substantially stronger about that on a laptop than I do a desktop. For desktops that, for some inexplicably stupid reason, lack the space for an optical drive, I have no problem attaching a USB 5.25" Desktop Tray-load form-factor optical drive as it will perform faster, more reliably, and will be substantially cheaper than the crap they were putting in the iMacs since the iMacs first got slot-load internal optical drives. Yet, I digress.
Here's the reason why there's hate for the new iMac: It's a Mac where form is valued substantially more than function. Look at the people in this thread. Those that praise the iMac are usually prefacing their comments with something about how beautiful it is on the outside. And while externally, it is one of Apple's most magnificent machines, when you bother to take one apart, you begin to realize that it really is their worst designed computer. The heating has historically been bad and it has only gotten progressively worse the thinner they make it. It got so bad that Apple had to repurpose the power pin on the 3.5" SATA drives that sends HDD activity to the HDD LED on PC desktops to be used to report the drive's temperature to the logic board because there was that much of a risk of over-heating. As a result, even if you were able to get a 2011 iMac open, you HAD to replace its internal hard drive with one made by Apple lest you have your fans revved up at full blast and your AHT always reporting failures; aftermarket drives were not an option. Compare this to literally every other Mac (in which you could install SOME form of aftermarket drive) and you see this is atrocious. Even if you are not the type to ever open up your computer, your iMac's hard drive will eventually die, and if you are not under AppleCare, a replacement Apple drive will cost you substantially more and yield you substantially less storage capacity than an aftermarket option. For a desktop machine, this is unforgivable. And really, this was done because they needed that thermal sensor.
The iMac has so many thermal sensors because, 2011 machines and earlier had desktop CPUs, desktop north and south bridge chipset chips, desktop (3.5") hard drives, and GPUs that are only found in thick Gamer Laptop PCs because they generate too much heat to go into mainstream computers like the MacBook Pro or the PC equivalents. Total that up and you have a computer that generates way too much heat for way too thin an enclosure.
Personally, for this reason, and given the speculation that the 2012 21.5" iMac has a 2.5" hard drive and a GPU that is not the type to go in Gamer Laptop PCs, that might be enough to make it reliable enough for me to recommend to friends and family that would be in the market for such a computer. Remove enough heat generating components and the heat problem goes away. The RAM issue is annoying, but is more or less non-existent if the user maxes it out at 16GB at the time of purchase.
Though back to your question about why people are hating on the new iMacs, while I outlined reasons why the new 21.5" iMac could be reliable and viable where it wasn't previously, these are compromises that shouldn't be made on a desktop machine. Period. A desktop should be able to have all of the things that the iMac had in 2011 and then some; with a real desktop video card, with actual expansion and easy access. None of this, remove the glass with suction cups and remove the LCD panel nonsense...that's insanely ridiculous. Who needs that on a desktop and toward what end? Slimness? Sleekness? It's a freakin' desktop! Not an iPod, not an iPhone, not an iPad or even a MacBook Pro! It's a desktop designed to be more powerful than a laptop, not designed to be a stationary laptop in order to accommodate Apple's design anorexia. It is this disappointment that fuels whatever hatred that iMac users have. I myself was a two-time iMac user. And time and time again, I've been disappointed by the inability to upgrade my hard drive without performing a serious tear-down. The fact of the matter is that this 21.5" iMac is meant for people that aren't the type to open their computers, while the 27" iMac is meant for a sect of those people that want to get work done and not care about the inside of the machine. I am not that person. A lot of us are not those people, and really, why should a desktop require us to be that person in order to want it?
Only on the midrange and only as an option. The GPUs only have 512MB on the 21" which will be a pain for gaming going forward. Compared to the last iMac introduced 18 months ago, they are poor value, IMO. The 27" is better and will be beastly with the 680MX but it will be extremely expensive for what it is and outdated by new tech 4 or 5 months later.
Really, to be fair, I think the 21.5" iMac, at this point, is for the 2011 high-end Mac mini customer who, with that machine, got to have a discrete GPU. In most cases, a discrete GPU is better than an IGP even if it's neutered at 512MB of GDDR5.
The 21 iMac is not, and never was, a gaming machine. Any dedicated gamer knows that this isn't the right choice. And for casual gaming, a GT 640M isn't bad.
Hell, for casual gaming, the Intel HD 4000 isn't bad, but there are a lot of people who don't have the luxury of owning a Mac and a PC tower. Some are buying this round of iMacs to be both a good Mac and a good gaming PC (via Boot Camp, if playing a game that doesn't have a native OS X version). Toward that end, the 21.5" iMac is disappointing. Hell, even the 27" iMac is disappointing to a certain degree in this regard. For that kind of money, the kind of PC tower you can build is mind-blowing.
I could care less... much less... about what others think of it.
For me... it's an incredible machine and worth every penny.
I will be buying a new maxed out iMac this December.
Some of the people who post on these forums seem to be immature and whiny about ANY new Apple product. Their arguments are completely benign.
"What's that?"
"Oh I'm terribly sorry to hear that you wanted a ODD on the new iMac."
"I would suggest that you purchase the optional ODD as an alternative."
"Huh? You don't want to?"
"Well there are LOTS of other PC manufacturers out there. Maybe you should give them a shot."
"What's that? You love OSX?"
"Then I would suggest that you purchase the optional ODD as an alternative."
"Huh? You don't want to?"
"Well there are LOTS of other PC manufacturers out there. Maybe you should give them a shot."
"What's that? You love OSX?"
Rinse and repeat ad nauseum...
Some of us love the operating system, are even reliant on it for specific functions, but would prefer not to make the kind of sacrifices that Apple imposes upon us. Retina MBP is rad, but do I really need it to be so thin that my RAM is soldered onboard? The 2012 iMacs look stunning externally, but do I really need it to be so thin that I can't get at the RAM and have to grin and bear a 2.5" drive on the 21.5", and do I really need it to be so thin that I can't have proper heat dissipation or cooling while also enjoying a full desktop GPU. Do I need the design to be so sleek that I can't get easy access to the internals of the machine like I can on an HP Z1 or...dare I say it...a proper desktop? No, I don't. And you don't either.
People are upset because they like Apple designs and the OS but they want a different implementation of the hardware. We're not haters, we're just people who feel like we're making a compromise whether going with Apple or another option when it doesn't have to be that way.
If Apple were as focused on performance and upgrade-ability as they are on design, you might well have the perfect product.
DING DING DING! Seriously guys, this guy just answered the thread. Any ignorance of this post and its point is simply arrogance and ignorance.
I own a 2010 MacBook Pro. Since you said its for all round family use, I'll compare. The MacBook Pro does everything, including casual gaming very well, eve with inferior specs. I even do 3d modelling and its not a problem. I can't really see what is bad about a GT 640M. It's still good
For a "low-end" Mac, it's fine. For the cheapest new Mac you can buy with a discrete GPU, it's plenty. But for a desktop costing $1300, it's lacking. Going from any Mac mini, MacBook, 13" MacBook Pro, or MacBook Air, that GPU is an upgrade, for sure. But again, it's a desktop, and thusly, it shouldn't be so limited.
The only one's that are happy are the ones not buying the 21.5",
Really, I think a majority of the problems that people have with the 21.5" iMac can be solved by ordering it with the Fusion Drive and 16GB of RAM. At that point, for the average user, it's a fine machine. But really, I highly doubt that the heating and thermal problems plaguing the 2009-2011 iMacs are going to be gone with the 2012 27" iMac; if anything they'll be worse as the optical drive wasn't that large, and they slimmed it down THAT much more.
I have only been an Apple user since 2009, so I consider myself a newbie. Yet I see the following unmistakable pattern surrounding every release of a new iMac:
1. For a long time prior to the release, there is vast speculation, wish-listing, and pining about "when is it coming - not soon enough?" and "should I buy - should I wait?"
2. The iMac is released.
3. Roughly half of the postings at MacRumors show great love, and "I am ordering ASAP".
4. Other have of the postings hate it, and give forth various rants, about the deficiencies.
Only after the dust settles can a consensus opinion form. At the moment I am leaning towards ordering the 2011 refurb. But will wait and see.
Really, you have two camps of people responding to posts like this. One, the people that are so in love with the exterior of the design that they overlook the serious flaws with the internal design (though they don't care, they'll never have to deal with it). Two, the people that are informed enough on the problems with the design to have a negative opinion on it. I don't care how much time passes, those people are more or less static.
I used to be on the former camp until I (a) realized that upgrading the hard drive on my Early 2006 20" iMac, an action that would've given me at least two more years of life out of it, would've been a serious pain and (b) started working at an Apple Authorized Service Provider where I got to see more iMacs come in for non-accidental-damage repair than any other Mac and when I got to see first hand just how terrible the internal design of the iMac is compared to the other Macs in Apple's line. I'm hopeful that this new design changes that, but I'm not all that optimistic.
The 21" is for people who don't own screwdrivers. Or at least, care to use them on a computer. That's a much larger population than you expect.
BTW the RAM on that should be as user-upgradable as the HDD; we'll know how easy it is to take apart soon enough. Given that the stock is 8 and it only goes to 16, it's really not that big a deal..
I sort of agree with you, though I sort of don't. You're right that the iMacs are not for people with tools or people who like to open their computer (though opening a 21.5" will likely be no more or less difficult than opening up a 27"). The RAM issue though is annoying for those that don't know to order it with 16GB of RAM at the time of purchase as the time will come alone when they'll need more RAM and it'll either be impossible or really expensive.
I'm getting the 21'' because the 27'' is WAY to big for me and I'm not rich either

!
I'd imagine that this is a more common issue than people realize. Had I not inhereted money from a dead relative, at the time, I would've gotten a 17" Early 2006 iMac instead of a 20". Having been able to do that made my machine last me substantially longer than it otherwise would've.
You get a thinner, lighter more sexy machine for almost the same price +-
Also, a cpu upgrade and a huge gpu upgrade from previous models.
Sign me up.
People will never be satisfied and its stupid.
I'm sorry, since when did "thinner" "lighter" and "more sexy" matter on a desktop. This thing is supposed to sit stationary and do my bidding, not give me a freakin' lapdance.
People are unstatisfied because this is a machine that could be so much more than what it is forced to be under the limitations of a "thinner" "lighter" and "more sexy" design. Far be it for us to actually want our $1300+ computer to actually do things and do them well for longer than 3 years.
