My 770 is a back-up mini computer/entertainment piece to compliment my aging eMac G4.
Both are running Open-Source stuff,so the 770 is well complimented!

What's on mine? Lets see...

Games:

The standard plus Battlegweled,Blocks, and Tux Puck.
I like puzzlers.

Blogging: Mauku and Wordpy

I have many blogs,and both help me update Twitter and Blogger.

IM/VOIP: Gizmo5

Gizmo is a better IM client than Pidgin IMHO.
It's more reliable and has similar features when setup for IM.

Utilities: Maemo Recorder

Fun for voice recordings!

X Terminal and MWeather

For scripting and for local weather data. OWeather crashes. MWeather works great!

Music: Vagalume,Canola2,basic Audio Player,and Kagu

I adore music. I am addicted to Last.fm radio. Vagalume and Canola2's Last.fm plugin work great!
Kagu is the most reliable music jukebox on the 770.

Video: MPlayer,Canola2,And the basic Video Player

MPlayer plays my MPeg4's. Video Player plays my AVI's.

Photo: Quiver,Mirage,MH Shot tool,and Fickr browser

MH Shoot tool makes good screnshots.
Quiver is not bad. Mirage is faster.
Flickr browser is must-have.

Browser: Opera 8 and MicroB

Opera 8 is faster. It still loads like 50 percent of sites out there.
MicroB is for the other 45 percent of sites. Crashes and all!
I disabled the plugins for MicroB,and it flies!

I use a cheap 1 gig MMC Media card I got from Dealextreme for $4!
Works well and came with an adapter.
64mb of VM set,and the rest is for files!
