It's XP MS isn't supporting anymore. Give Windows 7 another year then that will be out the "window" as well.
I just learned my way around XP now I have 7 at work and XP at home. It's going to take me quite some time to learn 7. Probably just in time for MS to stop supporting it. Why can't we just keep the programs we like and are used to? Why are we forced to change?
