Hardware question from "fly-over country"

[Richard Owlett]

I'm in RURAL SW Missouri. A local used/surplus computer 
store is offering a Dell Latitude D620 (4GB memory, 80GB 
hard drive, Intel Core Duo @ 2.4 GHz) for ~$500. It 
reportedly has the majority of manufacturer's warranty.

Any comments on how suitable a Linux platform this would be?

TIA
