I agree with BB , if you don't need the features of XP Pro then save your money. Also uschie the advice your getting does apply to XP Home cuz I'm sure your not going to have a problem with your OS in an area that you don't have.

I'm running XP Home & it does all I need , if you need encryption or password protect....some free downloads are available. Run XP Home until it no longer gives you what you need , a hardware upgrade would be money better spent....or maybe a nice Game.

Have Fun
