So I bought a Basis Peak. After reading some reviews, I was pretty sure that the technology and software in this space is not mature enough to be satisfying, but I wanted a technology toy. The last cycle computer I had on my bike was a sad disappointment (in the endlessly-finicky and didn't really work department) and the selling point of the Basis is that it will detect bicycling automatically as an activity. Since that's much of what I do, and metrics makes everything more fun, it seemed like an obvious choice for my toy.
