We have not used the 150+ at all, all our machines are 166+ or 200+ - the only problems we have encountered have been legacy network cards and video cards, some backup solutions needed updating, but most of that stuff is really old anyway, and the customer wants to upgrade/replace it anyway.

Try setting up a dual-boot if you have enough disk space... - or removable/swapable drives to try out the NT os - it is NOT as good for backward compatibility as far as so-called consumer software - games and such.
