Just got this app a little while ago and it's very intuitive for an OG Droid user.
Things I like:
Hold a key for alt character instead of pressing the '123@' key and switching back.
Numbers are easily accessible.
Things I don't like:
The location of the backspace key. I'm so used to it being in the upper right that when I want to erase stuff I type pppp instead. It's also too close to the enter key.
It's a bit sensative.
some of the punctuation is oddly placed,
Otherwise, excellent app and worth the $.
XOOM'd from the XDA app.
