Advanced and experimental stuff like rotation and booting from SD cards will nearly always need xterm access. that's not particular to Maemo or Linux, just that you are playing with cutting edge and advanced topics, which is great as a lot of people are too afraid of the unfamilar to experiment. A lot of the work I do with Windows ends up as scripts and batch files.

The good thing is that you can always ask uncle google, which is what we do all the time. Maemo is not far off standard linux and a lot of the commands, tips and tricks work exactly the same.

The only way to remove stuffed applications, including themes, where you did not take a full backup immeadiately prior is to make a note on paper, or on the tablet, saved on an sd card or course of the apps you use. Then run a backup excluding the installed applications. Reflash and then restore and then reinstall the apps manually. We all should backup before any change, but there is always just that once where you think it won't kill anything or it's really minor - and it screws everything. Anyone who spends any time with computers who say they have never done that is either fibbing, or not doing as much as they say they are! They may only do it once though!!!
