Is it worth it upgrading from XP. I might need a new computer.
My view is that you're going about this backward. A change of
operating system should be driven by need, not just because
there is a new version available. Are you having a problem with
Windows XP that you expect Vista to solve? Do you have or expect to
get new hardware or software that is supported in Vista, but not in
XP? Is there some new feature in Vista that you need or yearn for?
Does your job require you have skills in Vista? Are you a computer
hobbyist who enjoys playing with whatever is newest?
If the answer to one or more of those questions is yes (and your
hardware is adequate for Vista), then you should get Vista. Otherwise
most people should stick with what they have. There is *always* a
learning curve and a potential for problems when you take a step as
big as this one, regardless of how wonderful whatever you're
contemplating moving to is. Sooner or later you'll have to upgrade (to
Vista or its successor) because you'll want support for hardware or
software that you can't get in XP, but don't rush it.
If you were contemplating buying a new computer (and you say that you
might), I would unhesitatingly recommend Vista, but I think upgrading
to anything new (Vista or anything else) should only be done when
there's a compelling reason to do so.
