Task:Remarkable community projects

This is a subtask of Task:Defining maemo and is looking for volunteers

There are hundreds of community projects around Maemo, but some are especially remarkable, providing a unique contribution to the project.

Getting a list of these projects would help to

Improve their quality and promote them as ready to primetime.
Highlight to externals some of the amazing stuff the Maemo platform can offer.
Bring attention, testing, contributions, new users to them.
Indicate to Nokia what is really worth promoting in their Maemo related activities.
Cheer up the ego of promoters and contributors. :)

Criteria

Propose criteria to select projects.

Alive: Maintained regularly and available in the last stabe release.
Open: community feedback and contributions are part of the project - open source is a very good factor but not a must.
Stable: feature set complete, installs flawlessly, works, doesn't harm the system, secure.
Finger/thumb UI: stylus to be required only in exceptional and evident cases (e.g. drawing apps).
Decent design: visually attractive and/or simple interface that works just as expected.
maemo.org active: available in extras, complete information page in Downloads.

Add your comments supporting/against the candidates listed below.

Abiword: Abiword's another desktop application which has a really nice port to maemo. A document editor which is very powerful and lightweight.
Camera: This is the first 3rd party application I installed on my tablet.
Dates & Contacts: Both part of the Pimlico suite of applications, these allow me to use the N810 as a personal calendar and address book, with desktop synchronisation to boot.
Gnumeric: Gnumeric is a great spreadsheet application, and the maemo port has been very nicely done.
Maemo Mapper: The best map application for the N810 that I'm aware of. Can interact with lots of different mapping sites, including OpenStreetmap.
Maemo Recorder: Turn your N8X0 into a dictaphone. Very useful.
Numpty Physics: This game is educational, hard, fun. Made for the stylus.
Pidgin for Maemo: Instant messaging application, ported from the desktop.
Vagalume: Last.fm is my favourite music site, and Vagalume is my favourite Last.fm client.
XChat: IRC on your tablet. Nice port.
Xournal: A great notes/sketch utility. One of few apps that utilize the pressure sensitivity of the screen! Invaluable to create and annotate PDF documents on a pocket computer.
