Personally, I would re-upgrade to XP and save the Vista DVD for posterity.
Modems are cheap...but who uses dialup anymore?
Scanners aren't always cheap, but they are a lot less expensive (with better
resolution) than they used to be...
That's one of many reasons I only have a couple machines with Vista and a
dozen others with XP at home.
I didn't comment on the OS, I just put a new computer on a desk for the kids
(8 of them, age 4-15) and let them have at it.
Every one of them has been using a computer since they were old enough to
use a mouse.
You wouldn't believe the negative feedback from those children! They wanted
to stage a lynching party in Redmond...
When XP was released, I upgraded all my old systems from W98/ME/W2K because
I could see/feel the improvement.
So could the kids.
With Vista, I don't personally see any improvement, I see it as a step
backwards.
Using Vista is like getting in my Escalade and finding out someone put a
Pinto interior (and drivetrain) in during the night...
it might smell new, but why did they use all that vinyl and plastic... where
is my leather and wood? And what happened to my horsepower?
Even with two of those 2.3L engines, it just just doesn't match up to my
6.2L.
I know change is a part of life, but it has to make sense and provide a
tangible benefit for me to accept it.
With Vista, they made many changes that make no sense whatsoever and those
changes provide no tangible benefit to the average user.
Ask an IT planner what benefit you get from dropping Vista in an existing XP
network.
After they take a dozen Excederin, they may laugh at you...they may shoot
you, but most will just roll their eyes and shake their head.
