Regardless of what it says here, you can *not* get Windows Vista
anywhere. Windows Vista doesn't exist yet, and won't exist untill
sometime around the end of next year, at the earliest.
A beta version of Windows Vista will soon be released, but
there's guaranteed to be a large difference between that beta
version and the actual product when it's released.
Advising people that Windows Vista is available for them get now
is very much wrong, misleads people who don't understand what
beta versions are, and does a service to noone.
