Strange cause everything Ive seen says Win7 boots faster than Vista but thats it, nothing else has changed much speed wise.
You may have been looking at the transition stuff, 7 features on the vista base, as they swap over more stuff to the 7 elements its got faster, should get faster each month now till launch at the end of the year and all being well with the progress bung in the new kernal, which they should do if things keep on the pace. They say it wont just to cover their backs since they are having to rush it out.
