Viro there isnt any 7200 rpm decent hard drive out there...
the only good one is the Hitatchi 7k60. but it consumes more power, it is nosier and reaches sizes of 60gigs only...
a speed increase is allways wellcome...
a standard 512 RAm is allways wellcome.
a price drop is allways wellcome....
the 64mb card becoming a standard in the 12inch powerbooks is allways wellcome...
the bluetooth is allways wellcome... (it might not be useful now, but it will be in the future... if u use other mobile devices that is.... u might be a simple user that doesnt need it... )
tha brighter keyboard is allways wellcome...
the larger hard disks are allways wellcome.....
etc etc... i can go on.. but if u dont get it by now... then u wont get it ever
