As of right now, I have one application: Dial-a-fix.
It's pretty stable, for being an alpha-test, and it will be updated next month probably. It will remain free forever. Anyway, I would like to eventually make a few 'killer apps' that I could make money from. Problem is, I don't know what kinds of programs people need right now. Any ideas? I want to make *something*, I just don't know what. I'd probably charge in the range of $1-$10 (USD) depending on how 'killer' my app is. :P
