Looking the Intel Concept subnotebook really makes me think that Apple has fallen behind the design curve.
To be sure I've always lusted after tiny Sony subnotebooks (the X505, say) but asides from the lack of OS X (a deal-breaker to I) there's always been things I would have had problems with. The X505, for example, has a horrible keyboard.
Thus I've long been an advocate of the Apple subnotebook (many many posts

. An 11" widescreen as often mentioned would be the ideal size, any smaller and the full size keyboard has to go.
Looking at the Intel Concept there's a couple things I really like about it. First would be the removal of the bezel. Brilliant. It just looks so much cleaner then any other laptop screen.
I'd actually go one step farther and not only extend the glass but the screen itself to the edge. I'm not sure what the problems would be, but it should be possible to have the screen go all the way to the edge.
Second would be the keyboard. I actually prefer the look of the MacBook chicklet keyboard, but this comes in a close second. Not least because the orange glowing keys are awesome and a lovely piece of retro-futuristic thinking. Kinda puts the lie to Apple never including backlit keys in the 12" PB doesn't it

Now the gold trim is ugly, I'm not sure I like the mismatch in colours between the case and the interior, and the OLED outside screen and carry-strap bag are all silly ideas. But the thinness, weight, and screen are all things Apple needs to get on, and I wouldn't mind glowing orange keys as well.
My PowerBook 12" needs to be replaced in the next year or so (much abuse) and at the moment I'd prefer to buy another then buy any of the current line-up. I need low weight and small size, and so do plenty of other people. Further if Apple ever expects to sell stuff in Japan they need a subnotebook too (building in a 3G UMTS radio, and a one-seg TV tuner would be nice as well).
