It's just a big faux pas in this day and age of environmental consciousness really. In my country we used to joke that people would buy a new car because the ashtray was full. This reminds me of that.

I don't really care about the environmental consciousness, my issue is that presenting a product with a battery that lasts for years when it actually lasts 15 to 20 hours makes me feel like I'm being lied to.

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…
