Typing laggish sometimes

[nutrapi]

My intrepid seems to want ignore when I hit the space button quite often, as well as just generally lagging. I know I'm not the only fast intrepid typist out there, anyone else have these issues?
I've actually made sure I was hitting the button already, to the point that I can hear myself click it:
"andt he textw ill still sometimese nd up liket his."
It's generally not that bad anymore, because I've slowed myself down - it's just annoying. On my htc, and my palm centro, I was able to type as fast as my fingers would let me - and now I feel slowed down by the samsung.
