As an owner and former user of an F3, I really like the simplicity and ruggedness. I wish that Motorola had continued to develop it to address its terrible shortcomings: lettering was rendered semi-1337-style through old-school LED typography and it could not display an entire 10 digit number across its screen. I don't know why they bothered to support text messaging at all because it was utterly unusable.

I still keep it around as a hurricane backup as my iPhone SIM plugs in to make calls without issue.
