hmm XP has pro's and con's, 2000 has pro's and con's... conclusion: Use any according to your personal preference... XP was absolutely immortal on my PC, if you like having a "cowfield" as a desktop and some "fisher-price" looks... go for XP, if you are a "9de-8" guy... go for 2000.... both are stable, i would chose XP if i were you (but i dont like the "cowfield"!!!)
