"(it comes preloaded with XP MCE)"
Overall this is like buying a mobile phone with a sim card with an unlimited texts deal.But you never do texting!
MCE is designed for Home Entertainment Systems really.Ideally go for XP pro or wait for Vista.The best time to buy electrical goods is after the Christmas rush but taking care not to but a turkey like the one offered. Oh your in a rush!
No one is fully upto speed as to what will happen in reality with these vouchers.
