Never really had much problems with XP either. But that didn't stop me from trying out Linux. And I was amazed by the fact that this old computer runs twice as fast running it. Simple things as opening a folder, or just waiting for a menu to popup (ex: right-clicking, or going through the All Programs list), there can be a few seconds delay on XP, while when I run Linux, it's there instantly. Also, I've found that Linux is just much more powerful when it comes to customization. To give just one stupid example: you can have a custom "wallpaper" for every folder you wish and to do so, it's just a simple drag and drop.
As I said, I've never had real issues with XP, but tryoing something else showed me that it is always possible to do better.
