When Microsoft announced last year that they were discontinuing support for XP, I guess they meant it. I have friends who are clinging desperately to XP like a guy who refuses to replace his beat up Gremlin with a newer car. What it's about is evolution...like biology, tech and software evolve as well. It would require a massive amount of overhead to maintain support for XP as well as Vista and Windows 7. Every piece of software would have to be customized for 3 OS's. However lame that may seem to XP users, it makes good business sense in the long run.
