Xbox and Xbox2

I am not an Xbox fan; quite frankly I don't play any of the computer games that my friends devour hours playing on their computers. But I read an interesting article on slashdot.com (check out this website; it is really cool!) that said none of the games that worked on Xbox would work on Xbox2. In other words, Xbox2 will not be backward compatible with Xbox. What? How can Microsoft get away with that? You are basically forcing your customers to buy new games when they upgrade to Xbox2. Don't you risk alienating your customers? Won't this be viewed as another instance of corporate greed? Why risk that in the current business climate? You may even prevent them from upgrading because they won't think it is worthwhile to do so. I think it is a stupid move if it is true. The good news is that Xbox2 is due out only in late 2005. So there is plenty of time for Microsoft to rethink this and get it right.
