What Tax Software Do You Use?

r_jensen11 asks: "I know this topic has been asked at least once before, but seeing as how 6 years have passed, I figured the question is due again. It's about that time of the year again when we find out how much we owe Uncle Sam (or as in my case, how much Uncle Sam owes me). Software has changed drastically in the past 6 years, since the previous query I found on Slashdot, as well as many tax rules. Does anyone here use tax software other than TurboTax and TaxCut? I know that there are also online forms I can fill out, but which ones are accessible to people that use OSes other than Windows and Mac OS X? I'd preferably use a program that I can use off-line and store my information locally instead of using eforms, but if I have to resort to eforms, which ones should I investigate and which ones should I stay far away from?"
