No shit. How is the current state btw?
I suppose still not ready to be a daily driver to replace my normal phone?
I'd say that depends on your definition of daily driver and/or how much compromises you're willing to take. I occasionally see members at my larger hackerspace running around with those or other seemingly "unfit" hardware and not complain too much about it ;)
As for phone feature, reliability of that depends on reliability of firmware of the modem, which was always shaky.
