First thing, don't get XP home. Get XP Pro, you want NTFS.
Secondly, it works very well. They did a good job on it.
That having been said, I'm not sure yet whether I'm sticking with XP or going back to 2K. I like the clean & simple design of 2K, plus the straightforward security as opposed to the over-simplified crap that XP uses by default.
