If you like the new CM10 nightlies, but you hate the phone mode, you may find this zip useful.
It's a flashable CWM zip which change the default density from 160 to 133, which force CM10 to load in tablet mode.
The usual use steps are:
settings -> interface -> general settings -> show power off menu
Both CM 10/10.1 nightly builds are stable
and flash works only with stock browser when you enable addins in browser settings, not with chrome
The touchscreen is much more responsive and makes an illusion for much faster device
