Summary: When the buttons on my Garmin Edge 500 finally wore out, I replaced it with the 510. My wife really likes the Live Tracking feature (I use it with the Garmin Connect Mobile app on a Nexus 5). When I'm done with a ride, the Garmin Connect Mobile app automatically uploads my rides to Garmin Connect. Then Garmin Connect autosyncs to TrainingPeaks. And I have CopyMySports set up to send my rides from Garmin Connect to Strava. All very cool.
Summary: I upgraded from an Edge500 computer. Main reason was the live track feature so my girlfriend can see where I am during ride. Edge510 is bigger and heavier (around 30 grams) than the Edge500 but also has bigger screen. You can see more information on one page. A better resolution wouldn't be too much... Touchscreen makes the use easier and faster than the old version. Which is another plus.
Summary: ditched my Polar CS-500 and fell in love with a Garmin the 510 has all the features you will ever need and the Bluetooth is awesome. No problems after several months of use seems to be rock solid product.
Summary: The package set was complete as described upon receipt. I wanted to have access to majority of my ride statistics and had no problems with the screen interaction compared to other feedback I have read. The sync with the phone and heart rate monitor is perfect on my Samsung phone and had no problems with connectivity.
Awesome device, App, and Web application that tie it together.

Summary: The battery life is great, I can ride for about 24 hours total before the battery is dead (I don't call what the official specs are). This is way better compared to running an app on my iPhone, which I used to do (and also loved), but would kill my battery in an hour. This device speaks bluetooth and talks to my phone to and the Garmin Connect app, which makes sync'ing rides efficient and trouble free (and doesn't seem to make any real dent in my phone battery).
