I'm more concerened about what they will call "longhorn".
As you probably know, longhorn is only a codename.
XPs equivilent being whistler.
Another thing that concerns me is compatibility. I guess since it's just extending from XP that we shouldn't have the big problem that we did from the release of XP since it was moving from what most users of 98 and 95 would use, the fat32 file system, to ntfs.
Anyway, i'm more interested in getting my hands on one of these beta versions legitimately, i.e. not off somewhere like kazaa or other p2p file sharing networks. If anyone knows (which i doubt) of a way to do this, i would be most interested.
