The lagging is not the clockspeed or the RAM, it's the slow ass internal storage that is being used, when multiple things are being written.
Only way to "fix" that is to install a 3rd party ROM that does some of the things mentioned there. CleanROM in particular seems to really make this tablet sing.
Oh, right on. If a ROM can resolve the lag issues then I see no problem at all.
No-brainer, I guess I'll pick-up that $350 TF700 since it looks to be the same solution.
