I run Linux on all my machines, but have XP loaded under VirtualBox on all of them. I use it for WinUAE, and other things. XP is my favorite Windows version. I will keep using it until I can't, then I will use Windows 7. I like Windows 7 pretty good as well, but not as much as XP. As far as Windows 8, won't use it. I tried it for awhile under VirtualBox, when they had the free trial, and hated it. I think XP use will be around for a long time. They may not support it, but will still have all the updates available under Windows Update, to the point where support stopped. That just means there will be no new patches put out. I downloaded all three service packs, and IE 8, so I can upgrade it mostly without even going to Windows Update. I don't use it as a main OS, so, I am not worried about viruses and such from web browsing. I download everything on the Linux side. I do have Avast loaded on the XP, though, to scan downloaded files. XP is a great OS, and I think it's use will continue for some time. Just my opinion, though.
