"you didn't read the manual" is all well and good to blame people on for not knowing that you're supposed to hold the play button to send the rockboxed ipod to sleep because wow yes we love manuals but it feels glib in the face of: i have never have had to read apple's original ipod manual. it just worked. "sleep" was right there on the main menu and not guesswork
and even when i didn't manually put it to sleep it still didn't kill its battery overnight
