Tested the tab and am disappointed with the speed and lag of typing on it. If typing fast, it will miss a letter or two... Is there a fix like sensitivity adjustment for it or is it meant to be like that? Im able to type really fast on the Ipad's keyboard but when i was with the tab it was just ackward. I read online that typing in portrait with the thumbs is good but it was also a negative... anyone can comment on this? was really looking forward to it until i tested the keyboard...
