swype is an on screen keyboard that instead of typing on, you draw lines on and the software deduces the intended word from the pattern drawn on screen as seen here:

its pretty slick, i was using it on my hero before i traded to a TP2 it works really well unless its a word that's not in the phone's dictionary then you'll have to type manually, and the version i was using you couldn't add a word to the dictionary from the swype keyboard, i had to switch to the htc/android keyboard to add the word, hopefully they've fixed that or i just missed it
probably going to be the best bet for entering text on the Evo
