I liked windows XP, it was a good version of Windows. The problems at the start of the XP was terrifying, but with service pack 2 most of the problems were solved. Despite i like windows xp, let's face it, it is not getting any younger. Windows XP is losing popularity.
According to a poll i run on my site, 36% of my readers use Windows 7, and only 26% are using XP. The results of the poll may be not representative for the whole world, but they say something: Windows 7 is more popular right now. What happens ? The advantage that everything works on XP will go away. Software and driver developers will start to support less and less the "old" version of Windows and we will start to have problems.
