It depends on what that hardware is protecting. Perhaps for an on the go additional layer of protection that's pretty good. For long term savings, I'm less sold. That said, I'll be testing out the Block device as soon as it drops and letting everyone know my thoughts then!

UI for hardware could be a little more user friendly. If we could get the hardware UI to be as simple out of the box as blue wallet, but with as many features just under the hood, that would be pretty solid. Bitcoiners tend to put WAY too much info front and center rather than keeping it simple.
