According to AppleInsider, the entire trackpad will serve as one big button... after playing with my current MacBook's button as if it's a clickable trackpad works quite well... and it makes sense. In that case, my only qualm with the design is that the black border is too thick and I don't like black keyboards. Apple has shown that white on silver works with the current wireless keyboards. I'd like it to be an option, but with the black border it'd look out of place
Overall I don't think it's too bad... gloss is annoying but matte is ****. There's a reason why all mobile phones are now glossy... the old matte ones were impossible to see in bright light. Everything went grey. It will take a while for people to accept it though.
If the trackpad is truly clickable, we have that NVIDIA chipset, and this new screen doesn't add much weight, I'll be buying one.
What I find interesting though... is that it says it was taken with an iPhone. As an owner of one, I know they take MUCH nicer images than the one in the pic... Admittedly, I own an iPhone 3G, but I'm pretty sure it was decided that the internal camera has not changed.
