Garmin will definetly need to step it up in that department to remain in the game. There are some similarities, from what I've read, on the Fenix2 and the V800, and differences as well. Thanks for adding your comments as I don't have a Fenix2 so wouldn't be fair to comment. I'll stick to the 910xt vs V800 as they are both dedicated Tri watches and I have them both.
