To those of you that say the imac looks "dated" I have a 24" and each and everytime someone comes to my house and takes a look at that monster they cant help but be wowed. Maybe it just that most mac users have just gotten used to the imac look, but you have to remember that macs are still relatively rare compared to pc's, not that many people have imacs at home.
Even after so many years the imac is still leaps and bounds ahead of any pc in regards to looks. Sony tried to copy apple but failed miserably for a reason, they are not apple.
While the chin does take away from the 17" and 20" imacs, it looks just fine on the 24". There is really no reason for the chin on the 24", as it has more than enough room inside to accommodate the power supply, speakers and RAM without the need for the chin. I may be in the minority here, but the chin does add something to the imac, the computer would just look more boring without it. I am pretty sure that Apple has come up with chinless designs, but for some reason decided against it.
iMac Pros and Cons:
Pros:
Space saving
Sleek and Beautiful All-in-One
Good Power (will be a little better with Santa Rosa)
Cons:
Not upgradable
No 2nd HDD bay
I love the look of a Apple Cinema Displays, the Powerbooks/MacBook Pros and of course the G5/Mac Pro towers. I think the anodized aluminum looks great. But a Mac Pro is overkill for me, and the Mini a bit underpowered with a notebook drive. So I won't buy a Cinema Display, esp. since there is no built-in iSight (though I do have an original that I could hook on).
I can get by the lack of 2nd HDD in the iMac with externals, esp. with the FW800 in the 24". But I really would like to see and would be all over a 24" or better yet, a 27" iMac in aluminum. I also don't have a problem with the chin, as it is the same size and therefore gets less noticable from 17->20->24 and I would presume even less noticable at 27". It would be nice to shrink it and give the iMac an even border all the way around, not as trim as the Cinema Displays, but definitely closer. All that said, the power supply sits in the chin, since it would make the iMac considerably thicker to but it behind the screen. Though knowing Apple, I'm sure the next generation with see improvements. I just want it in aluminum and please, please, please, soon. As in tomorrow, not after the iPhone.
