Had it now for a few weeks just got my 64-bit version disc (havent installed it yet), I think its worth it (bought Vista Home Premium) however I dont think it would be worth to get the Basic version wich dosent have the new Aero interface.
Just a few small things i think is better over XP:
- Looks better
- The new file explorer is

better
- The gadget bar on the desktop
- Its Error correcting program(if a program stops functioning it contact the microsoft server and looks for a solution to the problem)
- So far havent had any problem with older games (Even got Hostile Water: Anteus Rising to work and that didnt work on XP)
- Start menu works better
- Better support for drivers
These are just some small things I like about it and FS works.
