Oh, man.  This is a really, really bad idea from Microsoft.  On the other hand, it’s going to mean some easy money for me.  Let me remind you, my friend, that my computer-fixin’ rates are quite reasonable.

“…Windows XP users, including the millions who have recently snapped up cheap, XP-powered netbooks, will first have to wipe out everything on their hard disks in order to install Windows 7. on their current machines. In fact, Microsoft doesn’t even call migrating to Windows 7 from XP an “upgrade.” It refers to it as a “clean install,” or a “custom installation.” This disk wipeout can be performed manually, or automatically during the Windows 7 installation process.

If you’re an XP user, the disk-wiping will cause you to lose your current file and folder organization, and all your programs, though not necessarily your personal data files themselves.
