All the comments about how it will be too expensive and difficult to source unusually sized parts make me wonder how they make something like the Hammerhead Karoo for $400 - an android device with a 3.2" sunlight readable reflective screen (supposedly even more expensive), custom software. etc. Is the market for a bike computer so much larger than that for a smaller phone? I don't think they're burning VC, it was crowdfunded IIRC.
