Hi

I'm using Vista Business on 2 laptops and 1 PC for a long time now, not any problem.
Neither do I see any problems show up on other PC's and Laptop's used by the company
I work for.
For use of older software, just remember to righclick the .exe file in programfolder
and set what compability for file to run in.
The problems I've heard of, are mainly because people run 64 bit Vista and get some
compability problems, both hardware and software.
Myself I run 32 bit versions to avoid not devloped and missing drivers etc.

Regarding updates, yes, if just installed Vista, you have to go through the update
prosess several times until you're ajour and up to date. Later it's usually around
every 10.th in month, and that you can choose to run automaticly.
Once in a while it also it happens there is emergency updates to repair new and urgent
issues reported or detected.

I agree that Vista did not run well at first, too early release, but nowadays, not
any problems.
Anyway, Windows 7 is just around the corner, many happy faces and reports about that
new OS version.

Cheers
