iPhone Release July 11, 2008

Apple is releasing its new version of the iphone at almost half the cost it was originally. My question is... is it worth it? The full touch screen seems to be cool, but how hard is it to text on the thing? I'm rockin' the AT&T tilt but its kinda of heavy. The new version of apple is suppose to be half the size of the first version along with other features such as faster internet and a better dashboard.
