Emulators work on the Lenovo N22 Chromebook
Install Ubuntu, using Crouton. Emulators won't work if the sound isn't, so purge pulseaudio and alsa-base, then install just alsa-base.
Kind of a slow Chromebook, but what do you expect for $140? The keyboard and touchpad are good quality. It has a nice texture on it.
Dell monitor looks better then the Lenovo's screen, but the Dell monitor cost more then the Chromebook. And the brightness was turned down again.
