I have a Toshiba laptop with a 3.2 HT processor and a gig of RAM. I bought a second harddrive and installed Vista Beta on it.
At the moment I agree with everything
PR has said in his post, it does seem faster than XP and yes the security issues are definately going to annoy some people, overall I like it and for the first time ever I will buy it soon and not do my usual of, wait untill the new OS is a few years old and has had the bugs tweaked out of it.
I find it quite user friendly and I do like the eye candy, installation and setup was a walk in the park and so far anything I have wanted to do including networking has been very easy.
