- The One Ring (Google Voice plugins from Extras-Devel) Be warned, there's a reason it's in devel, but it's awesome. You can feel like you're helping while you're using an awesome program.
- Mapper. It's already better than Ovi Maps in some ways. Soon enough it will be better in all ways, they say.
- Speedometer. That's the one that most of my buddies think is the coolest.
- msaber. Because you need it.
- FM Transmitter widget
- KOffice viewer. If there's a way it's inferior to the Docs2Go one, I can't find it. It's fine and free.
- DialCentral if you have a Google Voice account.
- Angry Birds. My son goes nuts over that one.
- All the Nintendo emulators.

That's my odd list. There are other threads about this around, but I get to be an early poster in this one.
