I have to say, I tried this app on for size, and didn't really like it. I'll admit, the onscreen keyboard is cool, but when cupcake comes out we'll all have that anyway. Plus, half the time I didn't get notifications for new messages. Now what good is a messaging program that doesn't let you know when you get a message?!?
On another note, I'm proud not to be a iTool, why would I want a messaging app that copies the iPhone? Just sayin...
