For now they're kids with good intentions that have landed a 'live one', let's see if they can run with it and have the stamina required for something like this.
10 years ago I would have been much quicker to jump in but I've learned the hard way to be a bit more wary.
An appliance, to be really reliable, needs to automatically store it's data somewhere else...like, say, a central backup service run by the company that sold the device. Oh, but now a central company has all your private data. Oops.
It becomes a case of who do you trust more, your family and friends - or a company somewhere. Besides, your mostly only storing information you want shared with family and friends anyway - otherwise why are you putting your info on this device in the first place?
edit: if I wasn't clear, the backup would be an automated thing. Only backing up information on peoples devices who are allowed to see it anyway.
