It is not something that I do mainly because I have found the screen to be too small for any practical use for my purposes and when needed, I have become a BIG believer in Live Mesh (
http://www.mesh.com). I rarely do not have a laptop with me and I always have a phone so I can connect my laptop using ICS and do anything on my "remote" PC.
That said, there has been a few comments on RDM+: Remote Desktop for Mobiles. Those that have used it, like it a lot! It is expensive ($40) but if this is something that you have a need to do then this is the program to consider. There is a 7 day trial so check it out.
