The number one thing is to make sure that all of the software is compatible without having to jump through a bunch of hoops. Law firms are notorious for using OLD software.

This is the killer. I'm part of a large (6,000+; 1000+ in my state alone) engineering firm; our IS team are currently about to roll out Win7 at the end of the month. We have a lot of software—particularly drafting and modelling software—that we rely on (with few alternatives), and all of their related plugins.
It's not that we don't want to move forward, but the cost of buying new tools (that may not be compatible with our clients'), re-training staff, etc - is possibly greater in terms of lost productivity than just dealing with XP.
Hardware isn't a problem though, as any PC from the last 5-6 years can run Win7 in an "office" environment; a bit less if you need to run modelling software. We usually upgrade on a 2-3 year cycle and a lot of staff are now moving from C2D/4GB/HDD machines to i5/8GB/SSD machines. Everyone loves the SSD's.
