You're confusing "people who want to get rich" with "people who want useful products". "People who want to get rich" are a significant subset of the HN population, and they are downvoting you because they remember Dropbox. You'll recall that Dropbox was met by "people who want useful products" saying "oh, I can do 90% of that with rsync". Your solution is probably excellent for someone who knows what they are doing, but it won't make a lot of money, and it won't sell to the kind of status-conscious fanatic minimalist who always needs a new toy to prove their minimalism. In fact, there are lots of caution signs around this product's website indicating that they aren't actually very good at the technical parts. I wouldn't be at all surprised to read a teardown showing that this is a low-end Android phone with an e-Ink display running a single shell program around the underlying dialer, SMS and alarm functions.
