The current iMac aesthetic is a timeless, minimalist design that will still look good in 30 years. The width of the bezels are inconsequential to its intended function.
The only thing that matters to 99% of us on this forum is an internal redesign that can accommodate and adequately cool a Core i9-9900K, up to 128GB of DRAM, up to 4GB of SSD storage, an 8GB AMD Navi GPU and that will allow the iMac to run at full speed without throttling excessively or sounding like a Blackhawk helicopter taking off when it's time for some heavy lifting.
I expect a sealed box like the iMac Pro, so I would love for Apple to find a way to replace those silly tape strips with a magnet system similar to the previous gen iMacs that allows users a way to add or remove DRAM at will along with a 2.5" SSD. I do not expect an M.2 slot, because Apple just does not do that. What would be really nice would be Apple giving us an easy way to access the innards along with authorized upgrades from Apple for those that decide to go with a lower sized PCIe blade. Even if it means getting an authorized provider to install it for us to keep AppleCare coverage. I do not expect a mini-tower/full-tower free for all like a Windows PC, but I also expect that I would not have to jump through hoops to source a larger PCIe blade to move up in storage.
Case in point, my Late 2013 27" iMac has a 3TB Fusion Drive. We ALL know that eventually that 3TB HDD is going to croak. I need more than a 128GB SSD in that PCIe slot...the computer is fast and does what I need it to do for now. I should not have to lurk around on eBay or a third party site like some crazed stalker waiting to snatch up a used SSD in a larger capacity, wondering how much life it really has left. Apple does not need to keep the parts longer than they normally do, but they could make it easier to find upgrade parts. Also $699 for a brand new 1TB SSAUX SSD blade seems a bit excessive for a replacement SSD, but I digress.
Bottom line...smaller bezels do not fix the issues of Apple ignoring the Mac market, when they need to be making some minor adjustments to get it growing again, which is was doing...outpacing most Windows OEMs in unit growth. Make no mistake, if I can transition to an iPad workflow, I will, but right now, it is just not there and no one at Apple can force it to be there, no matter how hard they try. I hope they are learning that a business cannot depend on one product at the expense of the other products, especially when it was clear that the Mac portion of the business was expanding as well, not contracting. It boggles my mind that a strategic decision was made to ignore the growth of a $25 billion dollar a year market. Yes, the iPhone sells more and makes more, but going all in belies a lack of understanding your customer base.
So, hopefully a new iMac is on its way soon, along with a new Mac Pro and a revised chassis for the MacBook Pro that fixes what is an extremely embarrassing situation at this point. I have had no problem with my MacBook Pro keyboard, but I would still prefer the Magic Keyboard scissors mechanism in a slightly thicker chassis.
Sorry for the tangent this took!
Viva la bezels!!!
