I've been using 98SE for over three years because that's the most my system could handle. I'm finally building my first system from scratch and I'm not sure if it pays to spends twice as much for XP Pro. I mainly plan on using my sys (P4 2.8 800FSB) for college paper writing, watching movies, playing a game here and there, and for playing around with my digi pix. Will XP Home do the trick or would I be better off with Pro?
