good to hear that there is plenty of positive hard reports back on W7.
Through the problems i have had in the past I've just been lairy of adopting a new O/S at the outset..
FWIW i know server 2003's issues and it remains outside of direct connection to the WAN. i have a very specific network set up and the set up is very tight.
i also use some specialist software that vista doesn't like and am loathed to experiment with it on a new o/s.. likely i will upgrade the vista ultimate machine to W7 and bench test it before considering a change out. all the computers have been either built specifically for their purpose and my two laptops are non standard..
as for HP printers / scanners.. agree the hardware is spot on the software is a pain.. but thats another story...
will be very interested to keep seeing your feedback on w7
