I installed SWYPE on the G1 but I have yet to use it and I am considering uninstalling it to give myself a little more room as the G1 has very memory onboard to begin with.
But the couple of times that I gave used it, I did come away impressed. A friend of mine just sort of reminded me about it tonight when we were discussing which Sprint 4G device he should get.
I had recommended the Epic because I had played with it before and found myself liking it very much. I suppose I was biased by the poor battery life of the EVO.
Anyway, SWYPE works great as he managed to get about 50 works a minute with it. That is quite impressive.
I am gonna try to get rid of something else so I can keep it.
