I'm all about form, not function. If a computer does what I need it to do, and is an enjoyable experience, I really don't care what it looks like. Gimme a big beige box, and I'm a happy guy if it runs like like a dream. Obviously I'm still new to the Mac family.
On the function side of things, a few things I noticed at the Apple store tonight...
I do like the black border and slightly darker color of the box. Then again, I've tried to watch a movie on a bright white iMac in the dark, and didn't like being distracted by the glowing case.
The black Apple logo is very high contrast, and could be distracting.
The glossy screen rocks in the right light conditions. It would work great in my office, but I have no lights or windows behind (or above/behind) my monitor. Movies on this screen looked incredible.
I have a glossy Gateway notebook, and absolutely hate it. I can't sit outside to work, even on an overcast day.
The downside of the glossy screen is that it could mislead designers and photo finishers... Bigtime!
