You might not always like the resistive touch screen performance vs the generally more responsive capacitive technology used on the iTouch/iPhone. For the same price I'd get the TP2 w/ keyboard on demand.
I'm thinking about getting my first smart-phone and since I'm on Verizon, I am looking at HTC. I have narrowed it down between the Imagio and Pro 2, but am leaning toward the Imagio. The cnet review said it was more of a multimedia phone but all I am planning to do is listen to music and podcasts not streaming TV or anything extra. It seems like a physical keyboard would be better for texting but i have an ipod touch and do not have that much trouble using the on screen keyboard. Any input would be great!
