I am considering 2 x60 models and can get these two units for the same price (almost to the penny). I'm not sure which is a better machine...what do you think?
Model 1 Intel Core 2 Duo T5500 (1.66gigahertz 2mb L2 cache), 12.1 xga display, windows XP pro, 1gb ram (1 stick), 100gb 7200 rpm hd, intel 3945 abg wireless, 8 cell high capacity battery.
Model 2 Intel Core 2 Duo T5600 (1.83 gigahertz 2mb L2 cache), 12.1 xga display, windows xp pro, 1gb ram (1 stick), 80gb 5400 rpm hd, intel 3945 abg wireless, 8 cell high capacity battery.
I'll be using this machine primarily for java/unix development when at the book store and/or on my deck.

I'm torn between the slightly slower processor and faster disk vs faster processor and slower disk...Thanks.
