I thought I saw someone, earlier this week, mention that MS or the computer manufacturers were offering free vista upgrades on their current PC's they have on sale with XP installed. Is this true. I was planning to build an HTPC, but found an HP a1640n that is nicely loaded and decently priced with media center installed. If I can get vista for free, then i may have to take the deal. But for whatever reason I didn't think to ask the salespeople at the store.
