I get asked this question on a daily basis so will post here.
I went into the store and sampled the models, remember you are buying an $800 phone so a store should be really helpful, Not there are much more models coming so this info is quite old.
The motorola has not Bluetooth or Ir meaning slack connectivity, otherwise a nice phone, nice keypad, shape and superb screen.
The nokia was loaded with features ans used Symbian OS and has a tru WEB browser (and you can get opera) shame the keypad is so small & horrible.
The Sony ericsson v600i had bluetooth, good coonectivity and NO expandable memory!!!!!
forgot it though it's cheap
Samsung looked quite nice and is very small, though I have never used a samsung so had no idea and heard of really poor battery life.
I ended up with the flagship SE v800, it had no limitations I could see and works superbly.
This is only a guide, you may not need bluetooth or have tiny fingers. i would have swayed to the nokia probably if it was smaller and had a decent keypad. (the cheap nokias have great spaced out keys (not 027's) and the top end ones are tiny,... why???)
