Not sure if it goes best here or not, but Hero Labs is a great toolkit for the Gamer with a laptop. I've been using it for 3.5/Pathfinder for over six months now and it's officially replaced all the excel spreadsheets I used to have scattered through my PAN. I also have the 4E toolkit, but I don't use it as much (not in any games) and they have toolkits for the Cortex system (Serenity, Smallville, Supernatural), Mutants & Masterminds, and Call of Cthulhu.

Well, if you go over and check, you'll see that they are working on releasing a SR4 toolkit for character creation.
Last update puts the release date sometime around Christmas. And I can't think of a better present to find under the non-denominational tree.
