Got the Service Pack 3 from Microsoft. And from what I heard, it’ll be well worth it. Why? Because most people will be ignoring Vista despite its Service Pack release (yeah, I think SP1 for Vista coincided with SP3 for XP).
I honestly don’t see why Vista needs to be so demanding with hardware. It’s buggy, it’s got conflicts with other hardware, it’s a pain in the neck. While XP does most of the stuff that you do (errr… I’m assuming you’re just like me who writes on a wordprocessor, does some computation on a spreadsheet and does presentations at school/work/etc.)
