I used texas calculatem from calculatem.com for about a year or so. Very nice software. It auto reads your cards and gives pot odds, outs, advice based on Sklansky's starting hands. (you can adjust tightness/loosness advice based on position and from the blinds) I had a friend that was losing $ on Party and I had him install it and follow it to the letter to help him stop making silly positional mistakes etc.

Won't work on more than one tables at a time but i would say anybody that uses this software is probably not ready for multi-table play anyhow.
