My girl and I have matching Red Sprint 8130's... I got the one I wanted, and she decided to get the same one... She thinks it's cute, I really don't care, I just love my Pearl
Grey 8110. I like the color. The keypads with the other colors seem ugly. I love that the dialing keys are bright white.
I really had an issue deciding between the 8110 and 8120. I figured that since I was buying an unlimited data plan, I'd rather have GPS than WiFi.
As a visually impaired/legally blind person, I have to say that RIM makes some GREAT screens for their phone, which I can see with no problem. Also, I cannot drive, so the GPS comes in handy to find what street I'm on.
I also like the half qwerty. The full qwertys are too big.
