That is strange. I have no keyboard lag either. As mgioia2 pointed out, only DCD and this ROM had no lag at least for me. All others had from little to big lag. I use my kb all the time - emails at work and SMS - and I am not experiencing your issue. Did you try it on a clean ROM before you install all other cabs/programs?

On another note - I also experienced the misterious black screen issue mentioned here. I pushed the power button and phone did not come on. Then I opened the keyboard and it was lit which means the phone actually was on but the screen was black no matter what I pressed. Soft reset fixed it and it happened only once to me so far.
