I tried out my new toy at the weekend 
It's very easy to set up and use. It got satellites quickly. It beeps at you if you forget to turn the time on when you start moving!
It shows current speed, distance and elapsed time on the main screen, and you can also view other info at the bottom (average speed, ascent, descent and cals burned), either choosing one of those or auto-scrolling.
You can have autopause, if you want (I don't).
You can then upload your data to Garmin Connect and have hours of fun geeking 
It gives you a map (which you can zoom), elevation profile, speed profile, you can view laps, you can do a "ride-through" on the map.
Evans are (still) advertising it as having a £30 cash back offer (which you claim direct from Garmin), but this is actually only available on the Garmin Nuvi models.
When I pointed this out to Evans (after I'd tried to claim my cash back from Garmin), they refunded me £30 - making the cost £87. Worth every penny, I say
