I've done an initial port of Gene Cash's python PIM programs to OS 2008. These packages should be backwards compatible with OS 2007 also. Download the .debs in order and the dependencies should be satisfied properly.
So far so good. Both installed with no problems. I've played a bit now with the To Do app and it seems to work very smoothly, causes no problems. I'm really glad you ported it, and I expect I'll soon be glad you ported the calendar, too.
Good job! (Good job, Gene Cash, too; it seems so far like a very cleanly made little program.)
I'll take a look at Spend It too. So far the porting hasn't been too difficult... but some details like the finger keyboard issue somebody mentioned might take some doing to track down.
I think I got python2.5 magically installed by some other app I previously loaded on my NIT... hopefully somebody else can provide some help for the easiest way to do it. If you look up pymaemo on garage there is a more complicated way to install it separately in red-pill mode: http://pymaemo.garage.maemo.org/installation.html
