I'm surprised the people involved in the company didn't see the price tag as a potential super turn off to customers. I'm the target demographic for this product, saw the price; gave a chuckle, and I'm a little curious as to how it made front page at that cost.
Never heard of Roam, but Dropbox and Evernote are old, established; brands and if I was to pay around the same amount of money anyway, I'd obviously go for Dropbox, something that's been around a while. Google Drive also offers a lot of space for free, and Docs sync is great.
A lower price is an excellent way to break in to a new market, and I'm not sure why the developers of this app didn't go for that. I like to support new developers, so this is a shame.
