If it lasts 15 hours of recording and you record on average 5 seconds at a time, that’s about 11000 activations. I think 5 seconds is a pretty conservative estimate, most things I imagine this being useful for would be more looks 2. Easy to see it lasting years in those conditions, but yes you could drain it faster if you used it very heavily.

This is true, but there's a big difference between saying "15-20 hours battery life, which is 11000 5-seconds activations, which last you a few years with 10 5-seconds activation a day" and "years of battery (btw in small text the real number is given). Especially since they mention that this project is hackable/you can do other things with it, knowing in advance you have something like ~100k button presses means some projects feel perfectly and some others won't really work.

Same issue Apple had when the iPod was new. How big is 20 gigs? Better put 150,000 songs instead…
