Didn't really have that good of an experience in the early days of Vista even though my first laptop was one of the first to come preloaded with it. The initial disk thrashing the OS did contributed to the perceived slowness of the OS, file transfer operations were slow (on top of an additional unnecessary dialog for deleting files requiring admin privileges), with the graphics drivers back then the DWM tended to deteriorate after a while requiring a service restart, etc.
Can't really place all the blame on a particular party. Hardware manufacturers dropped the ball on drivers, Microsoft dropped the ball on "Vista Capable" and the Ultimate Extras that amounted to little (plus minor annoying UI quirks such as the above which were resolved in SPs)...
On equivalent hardware at the time XP tended to be snappier - thus I kept a dual boot of install on my main desktop back then. Never had to bother with a dual boot since Windows 7 and same for 8. Now Microsoft is serious about optimizing Windows for speed and efficiency and it shows.
... but yes, back to the topic. The only relevant development time was that span of a bit over 1.5 years when the OS developed rapidly through CTPs. That would hopefully be the last time we see a Windows build evolve that rapidly between "beta" releases.
