Meh, when I get a new computer, I'll probably upgrade to Vista. On my current one, I'll stay with XP. Main reason is the system requirements. My current comp. wouldn't be able to handle that, though when I do buy a new one it of course will. The style looks nice, and most(not all though) of the features seem like pretty good. Is it really a giant leap though, no, tis more of just a souped up XP, but as far as I'm concerned, I like XP, so I'm fine with that.
I don't really see why all the talk though about how it's going to flop, and MS is going to start crashing. Even if it does flop, it wouldn't be the first time MS made an OS that didn't catch on compared to some of there others, and they've got the money to keep going on anyways, as XBox is becomming a bigger and bigger product for them all the time, not to mention their current dominance in the OS department, that they'll survive either way, provided that they actually release something better soon afterwards. In the end though, people will still buy Windows and MS products, because of the simplicity it offers, and so forth. For those more computer savvy than others, and familiar with Linux, it may seem strange that windows is so widely used, and may feel that Linux is just a short bit away from being a legit competitor, but really, there's tons of people who have never even heard of linux, and in the end, the average person who just wants to go chat with friends or family after work, and send email, is going to buy Windows.
