Princess Charmin' obviously uploads metrics to Garmin Connect, and having used that for about 7 months, I have become used to how it works, including when it doesn't work or take unreasonably long to do things. I can see that a number of my facebook (*goes to wash my mouth with soap*) acquantances are using Endomondo, and having signed up there to see what it's all about, I have learnt that it can automatically suck information from Garmin Connect and present it using its own interface. At an initial glance, it seems that Endomondo's user interface is prettier, slicker, faster and better than Garmin Connect.
So... Are anyone here using Endomondo? Do you like it? If you are or have been using Garmin Connect as well, which do you prefer? Why? Upsides and downsides? Spill the beans!
