Choosing a cellphone 2008

It's time again: two years ago I choose which computer I would carry all the time would be, and now it's time to choose a cellphone again.

This time, and after a really quick grep, I came out with this possibilities:

Motorola E1000 - UMTS 2100, Bluetooth v1.1
Motorola E1070 - UMTS 2100, Bluetooth v1.2 with A2DP
Motorola V3XX - HSDPA 850 / 1900
Motorola K3 - HSDPA 2100

If you have any experience or thoughts about any of this cellphones, please leave me a comment. I'm particulary interested in knowing

  • how does it behaves while being used as a modem, via bluetooth
  • how does it's embeded browsers behaves,
  • how does Opera Mini behaves there
