Vista Horizons

istartedsomething has done a comparison of running Vista in Parallel's Workstation vs. Microsoft Virtual PC 2007 beta. Interesting results:

Parallels started off faster by at most 2 seconds, but eventually Virtual PC caught up and ended up winning by 8 seconds. This has put my superstition about Virtual PC’s sluggish performance on the back burner for the while, until each product optimizes their products for Vista even further.
