I think the secret though is in reality, your phone will backup to the cloud every night (assuming you leave backups turned on and keep wifi enabled) so the transparent use of cloud data is where things like this get lost in translation.
Now the phone is smart enough to know the difference and only backup whats new, but if you record a few videos a week that turns into gigabytes very quickly.
Given the nature of their approach and the small initial investment in the hardware I can’t see them not wanting to get absorbed ASAP as a software play for a larger Android player.
