It's not a case of getting them to move to Vista as such, more to enhance the reputation of the OS, so that if you do buy it, or have to use it on a laptop that comes with it, then you'll do so knowing it's OK, not having the perceived thought that it's worse than XP lingering over it.

They're not trying to make people buy Vista (they're quite happy sucking up the sales through OEMs) it's more about protecting the name, especially as Windows 7 will just be another upgrade more than an overhaul (if you could call any MS OS an overhaul - you know what I mean though).
