I'm just curious why you recommend flashing the official 4.2 upgrade before flashing CM 10.1.
The Official 4.2 upgrade is the only Rom out there that eliminates the electric popping sound on key presses, and yes to your question about the ext4 partitioning format. I also like the battery performance and the Mutliuser option. The downside to the 4.2 upgrade is that you'll need to re-partition the internal SD to UBIFS (which can be a tedious process), if you want to go back to stock and Feiyu roms and there's a slight screen dimming effect on hard reboot that you have to press the power key after reboot, to make the screen come on to full intensity.
Edit: I've installed Nova Launcher
because Trebuchet (the stock CM10.1 launcher) loses it's settings every once in a while and you have to wipe the launcher settings in or to access the app drawer and, I went with Alloy Red theme
. I believe the issue with Trebuchet, is the result of an upstream bug with Jelly Bean, not the launcher itself.
I'm very pleased with how this tablet is running, using this setup. Kudos to Christian Troy!!!
