I installed ICS on my EeePC netbook which seems to get premium treatment all the way around in terms of Android x-86 and even back then when people used netbooks (and still do) to install a hackintosh setup.
It's probably the best hacker supported modern day computer around.
It's quite a fun experience and works rather well, however, sometimes the screen will rotate by 90°, although that seems to happen less now than it used to before.
Never really looked into that issue as a reboot always helped.
Right now it's my sole OS on my netbook simply because I didn't get GRUB to boot Android AND Ubuntu, so meh.
I can recommend doing it, although many apps are incompatible and hence uninstallable from the Play Store.
I have yet to find an easy way to install the translation layer for ARM dependent apps for x86.
A site with a tutorial used to have it but the binaries are gone.
Also, I'd love to finally get my hands on 4.1.
Might install it now seeing how it's been available for a couple of days now ^^
4.2 porting has started, too which is awesome news.
The JB version they released is based on 4.2 already. My bad. ^^
I say go ahead, it's tons of fun!
