I'm totally in love with being able to record rides. How I wish I could review in minute detail my rides from 30 or more years ago.
Having watched this thread develop, I haven't noticed anyone preferring a Bryton or similar over a Garmin - apologies if I've missed any. The debate seems to be over the respective merits of Garmins and phone apps, or nothing at all. Since nearly every ride I do is longer than 8 hours, and Garmin seems to be the unchallenged market leader for dedicated devices, there wasn't reallly any contest when I bought my first Garmin (a 200) about a year ago.
When I upgraded, I went for a 520, not particularly for its feature set, but for its battery life (better even than the 200 so far) and, from anecotal evidence, better reliability than models which on the surface seemed to match my requirements better, the Touring and the 810. So far both my devices have been rock solid.
So I'm in love with the concept, not necessarily with Garmin, but from what I've seen so far, they deliver.
One thing I always liked about the 200 was the fact it doesn't have a barometric altimeter. I can't see why, given time, elevation based on map data can't be made accurate enough for all purposes, and whilst for the moment I do see the case for using barometric data, ultimately it seems like a flawed concept. A world where everyone is using the same elevation data is my principal hope for the future.
