I just tried out
the Android 4.0 Tech Demo from 2011-12-06.
(It runs off the SD Card, write it to your SD card like you would a normal ubuntu release.)
Summary: VERY ALPHA
My setup:
* Efika MX SMarttop T03
* Class 10 16GB SDHC Card
* Samsung 2333HD 23" 1080p HDTV/Monitor combo over HDMI (it behaves like a TV over HDMI, it can do stereo audio over it))
* Logitech Cordless Desktop EX110 (keyboard/mouse on one USB receiver)
What didn't work:
* My cordless desktop, the receiver was powered but the keyboard/mouse didn't work
**** I had to plugin a regular wired USB keyboard & regular wired USB mouse
* No audio over either HDMI or internal speaker; didn't test analog jack
* Wi-fi (never lets you enable it in settings)
* 10/100 LAN (although support isn't part of vanilla AOSP)
* Bluetooth (never lets you enable it in settings)
* System freezes when the screen is going to go into standby after 1 minute of idle (mouse may or may not work)
**** Fix temporarily by rebooting w/ ctrl + alt + delete)
**** Fix permanently by going to settings > developer settings > keep screen on
* Power LED stays solid blue all the time
* At the lock screen it says "connect your charger"
* Switching wallpapers is all messed up
* It thinks it only has ~240 MB of internal storage & no SD storage, even though I saw that the uncompressed .img is 2GB
* If you use the dialer to dial a number, the dialer crashes (which is acceptable), but then it puts your screen orientation in portrait & it gets stuck (so everything is flipped on its side)
**** Fix by rebooting w/ ctrl + alt + delete
* It was built by the build machine "lumen", what a stupid name!
* And the developer who built it, "steev", spelled his name wrong!
That said, this is still awesome because:
* Everything loads very quickly (like the old android 2.x tech demo)
* Hardware accelerated graphics are working, not perfectly but rather well
* The background animation is fairly impressive
* This HDTV/monitor worked over HDMI whereas it does not under Ubuntu (it does under Debian armhf though; a genesi dev said it's probably because debian uses the framebuffer)
In all honesty, I'm more excited over my efika mx than ever before! Regardless of one's opinion on GNU/Linux vs Android, this is SO MUCH FASTER.
UPDATE: I did not notice
markos's post when I wrote this.
