It's likely enough I just pre-ordered one on February 5th 2016 hoping for March delivery, understanding as a software professional it could take them two days or two months to fix their bugs and ship.

Garmin's cycling computer user interfaces and bugs suggest those groups don't employ product managers who are active road cyclists.

Finishing long rides quickly requires being smart about pacing so you're fast and navigating well so you don't add extra miles; although prior to the Edge 1000 with two fields Garmin would not give you power or heart rate on a navigation screen. The ELEMNT includes up to 4 data fields on the map screen. The Joule GPS does 2, although it's breadcrumbs only without maps. Cellular phones do fine, although mine ran out of battery when I used it to drive to a ride, and I went from 40 to 5% over 40 miles being careful to turn off the gps and ridewithgps except when pulling it out for ambiguous turns.

Riding intervals the time is fixed and you only care about power and/or heart rate, although ending a lap on the Garmin only summarizes time.

My Edge 500 has always had bugs a serious cyclist would encounter, even with the final firmware version shipped years after launch. When I calibrate my PowerTap before riding but deal with other things long enough for it to sleep my Edge gets stuck on the calibration screen until power-cycled.
