Awhile ago, I had a hardware problem with my XPS M1210 (running XP Media Center) and while getting help from the Dell tech, I asked him about installing Vista.  He was n oncommittal about that, but mentioned that I would need to buy the OS from Dell, not a retail outfit.  Is this the case?  If so, are there special drivers, etc. supplied with the Dell package?

 

Any help would be appreciated.   Thanks.
