Decisions decisions... HELP

Last night my phone crapped out on me. I really loved the phone that I had, but I knew the day was coming. I had to Motorola Q, it is great, had all the features I wanted, but I bought it used from a 3rd party because m at&t upgrade wasn't eligible yet. The moto Q runs on the windows mobile and like any windows software it needs to be updated. Well that is why mine has crapped out, its time for a new one. The windows on it is bogged down, and there is new technology that is taking it out. Like I said I love this phone but I know if I get another one with the same windows mobile its going to crap out on me again in a years time. So here is the problem, I am going totally new, I have it narrowed down to 2 options: iphone, and the samsung impression. So I am turning to you bloggers to help me with my decision and pro/con list. I NEED your opinions please.
Thank you.
