I don't use my cell phone that much so a while back I switched to prepaid to save money, so might consider this for a lower cost way to check email on the run.
Of course $10-$15 would be better.
But the real killer for me is that the password button in no way locks the device-- no password, no pin. I can't risk losing a device with all my personal info on it. I'd reconsider after a firmware update adds that.
