I saw your post about looking to trade your machine for a smaller machine.
I recently got my Sony notebook back from warranty repair.
They had to replace the hard drive. :-)
The specs are as following:
Model: Vaio FS640/W
Pentium M 1.66
80 gig hard drive
15.4" glossy screen. No dead pixels
512 meg of ram. 1X512 + the other original 256's that came with it.
Intel integrated graphics. (128 meg of ram)
