...for doing tablety things and for development of course. It's totally useless, i can't do anything with it. From the moment it arrived, my wife is using it and i never saw it again except for making some configuration changes... ;)

Nice little device.

I got the chance to run my stuff on it at last...first impressions on the NVidia Tegra GPU:


  • It's faster than the Nexus S, but that was to be expected. It's not that much faster though. Performance in my RPG game is 30-60% higher (ignoring the fact that it renders around 2.6 times the amount of pixels).
  • All my shaders work fine. I didn't expect that at all... ;)
  • It has accuracy issues. highp in the fragment shader doesn't seem to be supported (just like with Mali chipsets). The rendered image is worse than what PowerVR gives you, but still acceptable.
  • Default zBuffer behaviour is laughable. It's always 16bit (there's no support for higher depth) and it's inaccurate as hell. You get z-fighting all the way if the factor between near and far plane is > 100. There is an extension that you can use to increase it (EGL_DEPTH_ENCODING_NV) and it's ok after doing so, but you have to write your own ConfigChooser for this. It should be default IMHO. The next version of jPCT-AE will include such a ConfigChooser implementation.
  • Coverage AA works fine and looks good. Performance drop is there but not that much...maybe 10-20%.

After all, it's ok but i would still prefer PowerVR over Mali or NVidia.

writing this from my new nexus 7  ;) pretty cute device except
* charging icon does not appear at notification area
* chrome and home screen does not work in landscape mode..

edit: no problem with chrome. it is the screen orientation lock

I don't get why that lock is enabled by default. Took me a while to find the setting to change that.

is your battery icon indicate charging status? mine do charge but icon does not reflect it

this may be handy, allows home screen to be in landscape mode:
Just got 4.1.2 installed on the Nexus 7. Home screen now works in landscape mode too.

I have a whole lot of Android tablets, but the Nexus 7 is the best one by a large margin. I just REALLY hate that they changed the settings icon.
