I still use xp on my main rig, w7 on my laptop. I absolutely loathed w7. Its slower, bulkier, and generally more of a hassle to get my fav apps to run. And here comes windows 8. Sigh.
I have Win 7 on one netbook that I use with some specific (and few) applications. The rest are XP with the exception of one running Linux. I think that the future for me will be Linux with XP as long as I can hold out.
I’m still using and am content with XP.
