- SimpleReboot (app that i wrote myself to shutdown a kindle completly, not just standby.. also allows you to reboot the kindle quicker)
- Leafpad (Texteditor for making notes)
- "Draw" App that allows you to make small sketches i then can save by making a screenshot (if i have quick ideas or want to draw easy things, nothing complicated)

- Gargoyle (old text adventure emulator to play old text adventure games.. not really comfy but hey it works)
