Leo Laporte reported on his Tech Guy program recently that many users were switching back from Vista to XP. With XP service pack 3 coming soon, more people are “downgrading” as a sort of “upgrade” since Vista is such a system hog. An independent study (I will have to find out who) reported that Vista runs anywhere from 50% to 100% slower than XP on the same machine. XP SP3 is expected to run 10% faster than XP SP2. Wow. Another rumor is that of all the machines tested running Vista, the one that ran it the fastest: A Macintosh. Go Mac!
