KTrove. Surprised not to see this app in the list. Let you install applications in your card that run only in main memory. (not all but many) and yes i works.
ZEditor. Absolute must, try other text editors too limited. simple, fast, can access any file. Maybe the app I use the most. Thanks!
ZBEDic. Amazing dictionary tool, the amount of available dictionaries is great.
ZSolitaire. I still enjoy simple games while waiting.
zKnights. Cool chess
Now as a developer I like:
apache2-php5-mysqlclient package. Let me test what i code in ZEditor
The embended SQLite database in PHP is great, lots of power, I stopped using mysql which anyway was an old version.
For videos, music, images, docs etc.. I just use the ones that came with full cacko 1.23 (have a c1000) excelent stuff
