the first five or so reboots of nitdroid was very unstable for me, i even tried to have it idle off overnight and the battery would just drain, but after installing apps to improve performance, SetCPU, ram optimiser, swap etc it IS STABLE I use it everyday, I have aDownloader running (torrent client) and have downloaded films and tv shows at 400kbs max while playing games no problem (I could never do that with Transmission in maemo)
