I run both XP Pro and Vista 64-bit Business. No problems with XP; Vista crashes at least once a day (although it recovers automatically without data loss) and I basically run Office 97 and Open Office on both, nothing too stressful. My Latitude D630 has the innards to supposedly be able to handle 64-bit Vista including 4 G RAM. Never should have ‘upgraded’ from 32-bit Business. I’m very disappointed w/ 64-bit Vista; glad it works OK for you, though.
How do I get a computer without Vista?? Macs are too expensive.
