I too like Windows XP but it is growing old with security issues that Windows 7 (for example) does not have. When support for Windows XP end on 04/14, just watch the attacks fly! The slime that write the virii and malware know how popular Windows XP is so they are going to prey on people who do not upgrade. They know without MS supporting XP, it will be an easy target.
I read that Windows XP with just SP1 attached to the Internet can be remotely owned by someone in around 20 mins.
It was a great version of Windows that is sadly showing its age...
