Motorola Q9m / Q9c

i was just curious if anyone wouldn't mind just giving me some incite on these phones. i'm gonna be eligible for my upgrade in a few weeks & i want to stick with a smartphone, just don't know which one? i already have owned the samsung i730 (loved it, just a bit bulky) & currently own the treo 700w. i like the treo b/c it was a bit sleeker than the i730. so moving forward, i don't know functionality & style wise how all 3 stack up... so i would really appreciate anyone's info & opinions of them.
