Spec's look decent enough, I use CAD '05 on my Thinkpad™ laptops, '07 on desktops.
All older, spec's older too. All work fine. All XP Pro SP3.
My Thinkpad™ laptops have 14" screens, crystal clear.
This is for portability. I hated carting the larger 17" screened laptops I had in the past, this shoulder, the other shoulder, back 'n forth. Plus, the battery charge was shortened somewhat to power the larger LCD screens.
