Now I know Dave from Blogography is going to disagree with this but:
I've won an apparently legit copy of Windows XP on ebay for £26. This means I can finally put the hard disk that I got for Christmas in my PC. I've treated myself to 256Mb RAM too so I will have a PC with a 200Gb hard disk and 384Mb RAM. :)
It also means I'm probably going to be spending ALL next week setting up XP. Great (not).
