"Mer is an outgrowth of Nokia's Maemo environment, designed to flesh out the tablet-centric operating system into a full-fledged Linux distribution suitable for embedded and desktop systems of all description. The project's genesis was an effort to back port the upcoming Maemo 5.0 release to no-longer-supported Nokia N800 and N810 tablets, but it has subsequently evolved to run on BeagleBoards, embedded navigation devices like the Pocket LOOX, and standard x86 hardware."

alot of good programs work well with mer since ubuntu packages now work on the n810 like wireshark and many more but there still is no battery monitor :(
oh well well i'll be waiting for that key component
my next project for my n810 will be to load gentoo on to the n810 which will be a fun task.
