I have just finished "porting" (well, actually there wasn't so much work to do) my first application to android, which is the well-known unix command line editor joe (see http://joe-editor.sf.net if you don't know it). If you want to try it out on your phone, I have put the binaries and a short installation instruction up on:
To be able to install it your phone has to be rooted! The application runs very well on my installed CyanogenMod. If you try it out please leave some feedback.
