Good after the OTA updates, was afraid it would be too big but it's not. After the updates, the battery will last all day on WiFi with minimal usage. Have not tested phone functions, but Google FIT, RunKeeper (even off network), Gmail, Exchange (after installing Exchange Services APK manually), Google Play Music, Dropbox, Google Now (voice), Google Navigation, and even Hangouts works. The round screen used to cut off many of the app buttons, but after the update, the major ones are more squared off and usable. Not as dorky as I thought it might be either, looks pretty neo-classy.Cons: not waterproof, straps not changeable (Antenna's are integrated)Semi-cons: Wish you could dim the screen more than the 3 steps, stock "launcher" weather is in Celsius, and swipe left to calendar - the actual appointments have no background and are hard to read. Only 1.3GB of space once you have the apps installed but don't really need much unless using for music while running with no internet connection.Tips: Let GPS lock on with free app called GPSTest in Play store, in open air for about 10 minutes. Once that has locked, other apps will work from that point on. It would never lock while moving or indoors prior to getting first location lock - it will persist even after reboots.Swipe up from the bottom for notification bar and wireless controls.Don't expect it to replace a real phone, but it's great for quick updates, or syncing information.Set charger dock on a vitamin bottle, so the stiff straps don't interfere with charging (which is magnetic and fairly good).
