Hello everyone

since the day that i got my n900 i never saw it as a normal phone or smarphone it's literally a laptop so i just wonder can i fully customize n900 to make it just like any linux destro i mean to delete everything and mount all in the "/" directory and i don't want to have the Mydoc folder + is it even possible to create a customized user and not the defaut username "user" basically is it possible to make it a true linux destro

Thanks
