They stated quite clearly then that they where getting 4000 new faults reported per day after the release of Vista so while it was tested by Beta Testers it was by no means a Fault Free System.

There is a very good reason why all IT professionals say Never adopt any New Microsoft OS before the First Service Pack. They are in no way implying that all of the problems have been fixed just the really nasty ones that slow down work and cost companies lots of money have been fixed.
There is also a very good reason why most companies are still running XP or have just moved to 7 bypassing Vista completely and that isn't because Vista is Rubbish just that their Upgrade Cycles do not agree with what Microsoft thinks that they should be.
