    Just got one of these a few days ago, the OEM version. These are my observations so far:

    Nice tablet. Well worth the price.

    Full 2048 x 1536 rez doesn't work that well. Mebbe driver prob, or hardware limitation: it runs out of memory quickly and goes into OOM purgatory, becoming unusable and needing a reboot. Full rez looks fantastic tho.

    "Normal" 1600 x 1200 rez works ok tho free RAM is much lower than with my other tablet, a Ployer Momo8 Speed which is also a Rockchip RK3066 device. After a bit of use get slowdowns when it scrounges for memory. Normal rez looks pretty good.

    Battery life is fantastic. Am getting like 10hr or more on time per charge.

    i have it rooted, but can't change CPU settings; it won't change governors etc. (i can with the Ployer so it's not the apps i'm using).

    Wi-Fi is a bit flaky with my router.

    Overall a nice tab that's easy on my eyes. i'm using it all the time.

    Nope, not the apps. T'was me. i reinstalled SU and the CPU control apps and it works now: i can change the governors and settings.

    Edit:
    It's too bad the video driver (hardware or software) seems to be problematic. If they ever fix it this would be a really fantastic tablet, all of these Retina screened RK3066 ones.

    Plugged in a Philips 32GB class 10 microSD card (at least that's the brand printed on the packaging). Works fine.

    Connected it to a few random bluetooth keyboards, they all work fine with a tiny bit of lag, however tablet battery drain is higher than i expected.

    Lets hope Yuandao comes out with drivers for this tab that stop eating up all free memory. That'll go a long way towards fixing all these issues. It is otherwise a nice tablet.

    Is there an active forum somewhere for RK3066 devs and hackers? i don't read chinese so am hoping there are english forums for it.

    --i took mine apart and it has an aluminum back case: that aluminum piece on the back is actually the rear case. The plastic all around the back edges is just a bezel, a rectangle of plastic trim stuck on with double sided tape. It hides the screws that fasten down the aluminum rear case to the plastic front case.

    The li-ion polymer batteries inside look like good units, at least with mine. The circuit board is laid out well, assembly inside is fine.
