I built mine about a year ago (check sig) went with xp as I new it well and was reading loads of bad reviews about vista .
The original plan was to get a 2nd hard drive with vista and dual boot but never felt the need .
Are you honestly serious, you never got Vista because of what you read on the internet. Some people online make Vista sound like its a totally unusable OS, for me that's reallt unfair as its a good (on x64 IIS takes a bit of tweaking to get working - classic ASP not activated by defalt???!!!).
For me, Vista x64 here. Have XP Pro installed too on multiboot, but haven't loaded that up for months and months. Only program I couldn't get working in Vista was flash media server, so had to fall back to XP for that

It definately goes to show that you can't bash vista unless you've given it a good go, as I was a hater for a while too
