DC has a birthday coming up and asked for one. Apparently a lot of friends have it. I have no idea what it does other than telling you the weather or spying on you. According to DC it does 'everything' 
Is this actually something for kids (DC is 10) and if they have one in their room, what do they do with it? I read about it but really none the wiser. DC has a tablet computer but no smart phone (if that helps in terms what it can be used for).
Thanks.
