It's really high time Apple re-designes the iMac so an actual desktop GPU can be used, hard-drives/SSDs can be easily replaced and upgraded and to refresh the look of the iMac.
The glossy screen is annoying, though as a long time user of CRTs it isn't anything that I'm not used to (after using CRTs with their glare for almost 20 years) but I do think it is a step back and unnecessary.
The mobile GPU is really annoying. The iMac is a desktop machine and yet is chained down to laptop graphics. One of the main benefits of a desktop machine is that they are a magnitude more powerful than laptops, and the price paid is that they are stationary. While iMacs sort of bring the worst of both worlds - because the chassis just doesn't support desktop GPUs.
The lack of a Blu-ray drive is bewildering. Though it has been upgraded from a "bag of hurt" to "mafia" which indicates Steve's recognition of the ability of organization by Blu-Ray, one imagines.
Honestly one of the biggest turn-offs with this new iMac is the Superdrive. It has no ability to present 1080p videos on a 27" high-res screen. There are literally discs available in the store that I can't use because I have only the latest and greatest Macintosh. Not because of any hardware reasons, Macs already support all hardware and software DRM and in fact use it for Apple store videos.. it's just that it happens not to support BD decoding.
The discussion of whether optical media is dead or not is completely uninteresting while iMacs and Macs in general actually HAVE an optical drive. They just have the optical drive of the last century. In fact it would be a heck of a lot better if the iMac had been available with an optional BD drive, even though it *couldn't* play any BD movies, but just burn BDs. Even that would be better than the "superdrive".
In the end, there is still no BD because Steve just doesn't like BD. He's fine with DVDs apparently.
The rest is all pretty predictable (and nice for what it's worth) but unimaginative and without any apparent vision of where the Mac is going as a platform in the future.
Here's my prediction of the next iMac upgrade:
It will most likely:
- get the Ivy Bridge chipset (still all quad-core)
- put a second Thunderbolt port on the 21.5" iMac as well
- retain the already familiar flatpanel form factor
- offer even bigger SSDs
- silently add USB3 support, since it's already part of Ivy Bridge
- still no Blu-ray drives, but still superdrives
- still use a mobile GPU
It will be released around march of 2012 and offer the trackpad as a standard, but for a small fee you can choose the mouse.
