I pretty much knew the macbook was going to look along that line, it was a natural progression with the macbook pro design. I do like the white macbook and could probably get away with it but the idea of white and the way dirt and grime would gradually mix with it puts me off - black does too tim
It kind of settles it in my mind that an i7 based macbook pro is coming though as the only real differentiator between the 13" macbook and the base 13" macbook pro is the enclosure, illuminated keyboard and slightly faster cpu speed.
That mouse kind of looks funky but I have a feeling that would be damned uncomfortable after a while.
edit - don't forget the mac mini with os-xserver, not bad for a web server really although maybe a tad overpriced.
Although the mouse is all new and fandangled, I hate using the mighty mouse they have at work, the little 'nipple' scroll always breaks and they are so clunky.
I have standard mice left older from older pcs and none of they have lost functionality or the ability to scroll. For me, practicality over looks wins hands down!
