Welcome to the forums!!! And welcome to the land of Maemo There are looooads of things you can read up on, so may take you a few weeks, hehe. Do not worry about the linux part - i started with no knowledge whatsoever - only way to learn is to try Best starting point is here - http://talk.maemo.org/showthread.php?t=36978 Then there are a few more places The Maemo5 101 The Wiki FAQ - Frequently asked questions Searching N900 on the wiki brings up other juicy pages too Those should be good starters edit - if you spot someone with Maemo Greeter in their signature - feel free to message them for help (Or me lol)
