I'm thinking of going with two different generations of HT OSes here. Right now, I have Win XP MCE 2005 on my HT rig right now, with a 500GB Seagate. On top of that, instead of flat out upgrading to Vista Home Premium, I thought I'd just buy an OEM copy of Vista Ultimate or Home Premium, or whatever else, and just slap that onto a second hard drive, like maybe another 500GB. I'm wondering if it's better to have a dual-boot, or if I really should go with an upgrade to Vista Home Premium. Should I trust Vista just yet? Think it's more stable than it was a year ago?
