I myself got a chance to "sample" the RTM release through a friend. It is a system resources hog! My friend has a sempron 2800 laptop he had it on and it rated his "windows" expierence, the level and tools vista uses and can be used on the PC, a 1. Another words, vista would not even load all its features on my friends computer becuase vista thought it was too old. Honestly, I am looking at linux much more these days.
