What OS are you using right now?

I'm using Windows XP. What about you?

I'm using Windows XP that looks exactly like Vista.

On this laptop, as well as my backup laptop, I am running Windows XP SP2.
On my primary desktop, I run Windows 2000.
On my backup desktop, I run whatever's on hand (FreeBSD, Ubuntu, and Damn Small Linux have all crossed its hard drive).

Sabayon Linux + Beryl

Windows XP SP 2...not going to touch Vista..

Windows XP SP2, as Vista is so new it won't run on my pc (512mb ram).

If you want your XP system to look like Vista, but work like XP, get the Vista Tramsformation Pack 7 (I think it's 7).

Windows MCE 2005 - Laptop =)

Desktop - Vista Ultimate
Tablet - Vista Business
Laptop - UbuntuI don't really see why so many people carry on about Vista. Yes, it has problems - all new OSs do - but it also has added functionality. And a lot of the things that people whine about so much can simply be deactivated.
