I've probably been hanging with the wrong crowd, but I don't think defrag is particularly important in XP with NTFS. Even the worst cases I've ever seen (No defrag for years) benefited very little from defrag, performance wise. I check every few months, and follow the "analyse" recommendations. I haven't checked the Vista defrag in a while, but I believe there's been some changes and it's an automated background process.
