Not sure why Apple had to make the Al iMac have a black boarder, however I am not taking too well with it. They should have either made the entire computer Al similar to the MBP or keep the back border and use a darker Al composite. At present the Al iMac is the worst compared to its design history.
I beg to differ. In fact, apart from the G5, I think this is the BEST iMac update they've had. I've seen a 17" Intel White iMac at school and gone home to my alum iMac about 30 minutes later and I honestly say that the alum iMac is MUCH better looking - and not just because I own one. I think the black border gives it a much more interesting design while still retaining the minimalism of Apple designs. Really, it's not bad. When I saw the unveiling pictures, I though "They look really ugly. REALLY ugly" but the design grew on me. They look SO much better in real life. They're beautiful and really aren't a step back in design. They're so nice. I really cannot agree with you in the slightest! Unless Apple comes out with a design that beats the current iMac in two years, I would place my bets on this being the nicest iMac design in competition with the G4 (Mainly due to it's bubbly character). There are literally no design problems with the current iMac at all. There is space for improvement, don't get me wrong, but there are no problems.
This is quite apparent with the iMac G5 and the Al iMac, the only other direction the industry can go in an all-in-one design is plaster the components as flat as possible to the screen. This design of the iMac is already stale. Same goes for a laptop, you can only make it so thin or rotate the screen and presto you have a tablet. Nothing new here folks.
Well there is nowhere else to go. Apple managed to create an elegant design for their all in one and it's as compact as it can really be. Until Technology advances, all they can really do is make it as thin as possible and upgrade the features (I.E. Add a touch screen). You can't improve perfection
