Troul Posted: how fragile is the E ink phone? Is it one drop away from being a paperweight? I'd like to think that the big names that make the bicycle computers expect the head unit to be skidded across the pavement doing 20 mph+ at times & maybe accidentally stepped on/ran over... I haven't tested the durability out, but that would be my expectation. Whereas a phone.... I'd at least expect some water resistance, but falling off a bicycle going 20 mph... not expecting a good outcome.
None of them are listing any waterproof info. I'm considering a Ziplock bag. I am also considering a new upstart bicycle computer made by
COROS It is inexpensive and has much better battery life. Then I could still use an E ink phone. In fact the solar on the COROS DURA is good enough that you might not need to charge it at all.
