I think its great!!! To all you defunct Apple users, gone to super Windows Build my own Android super Win8 Tower able to handle all things including NASA at half the cost, PEACE OUT!! 
Unfortunately, I need a workhorse, and the iMac just doesn't fit all the qualifications. You can't be mad at Ferarri for not making a pickup truck I suppose.
is their any point buying imac in nov/dec .. with haswell coming out in spring 2013
Haswell will have performance improvements, but it gets those in part through new instructions such as AVX2, FMA, etc. It will take a bit for the performance capabilities to be realized. It's largely the graphics that will improve the most, and they also anticipate a general price increase due to feature sets-particularly laptop processors. I'll happily eat crow if I'm wrong, but my guess is that Haswell isn't going to magically change computing anytime soon. You'll probably not notice the difference to be honest.
My understanding about the mobile graphics boost Haswell will get, will be with Integrated video. And these would not affect Dedicated video cards. So Mac Mini's == video boost, iMacs == no video boost.
But I could be wrong or thinking of Ivy
The Fusion Drive technology is different than the hybrid drives on the market today. The current hybrid drives cache a copy of the file or application on the flash portion of the drive for quick access. The Fusion Drive for Apple actually moves the files or application back and forth from the HDD to the Flash drive based on usage. It's a little different and of course, a lot more expensive than a basic hybrid drive.
My mid-2011 iMac has a factory SSD and I keep my apps and documents on it, with photos, music and movies on an external 4TB HDD because a music track or movie won't play any faster off an SSD than an HDD.
So I'm a bit worried about Fusion moving media to the SSD and moving applications to the HDD based on my use patterns, which means that when I do want to fire up one of those applications, it will be "dog slow". I'll be watching the benchmarks with great interest.

- Smaller/thinner - Who cares it's a desktop.
- GPU is made for a laptop, for gamers this will show it's age quickly.
- FusionDrive - time will tell how well this works. 128GB SSD feels small.
I may pull the trigger on the current one before December and get the integrated SSD/HDD configuration. Would not buy this new one over a laptop or laptop with ACD. No optical drive??? On a desktop? Seriously?
This would look nice sitting on a desk but in functionality would fall short for my needs.
Wow what a let down. What is the big bloody deal with going thin as that for a desk top. Major fail apple.... And it took you that long to come up with that
Wish I had bought now in July. Think I'll just pick up the older 27" as there should be a fair few for sale now at a decent price
