Tasky!
The dynamic duo of Calvin Gaisford and Boyd Timothy have unleashed Tasky onto the world, which they worked on during Novell's Hack Week.
Tasky is a simple TODO app for the Linux desktop, though I think the real awesome bit is the integration with Remember The Milk, an online task list. I really like RTM's features, especially the Firefox plugin for Gmail, which is really fantastic. The reason I like tasky is that I can have a desktop application that talks to RTM which I can "Always on Top" on my second monitor and have it in my face all the time.
Like any new project, it is very young and missing features, but if you use RTM and check out Tasky, you will quickly realize the potential here for a great tool. For example, someone has already written a backend for Evolution tasks. I threw up some ideas for future work here.
Join the tasky google group for discussion; get the code here, and feel free to jump in.
Edit: Misspelled Calvin's name, fixed. I guess I owe him a beer for that one.

C# :|
(it makes developers argue lots, and lots, wasting lots of time from what I see)

Jorge, thanks for mentioning; I've been meaning to look up any desktop applications that sync with RTM (I don't keep Gmail open all the time) and this looks fantastic.
