For the total view, I think 12.04 is the most stable version except default desktop. This meaning is that if you will clean-install from zero then the system is so stable.
I tried to update from 11.10 to 12.04. The updating was completed. But it was not stable especially x-windows system. Usually, I work on ubuntu and intelli-j. So, x-windows system's problem is critical for me ^^;;

I have linux machines but it has many risks for flashing rom with linux machine.
I thought that I should wait for real release for my phone. The first release was last april for US version. And, I waited almost 1 month. However, it could not get new release. This me…
