Having to worry about your toothbrush's compatibility with your mobile phone / tablet - what a time to be alive
Any guesses how long it will be before it needs a firmware update to fix a security flaw, or we find out that its telemetry has been spying on us and saying when the best time to stuff adverts in our faces.
I'm wondering how well the user interface will work - the screen will presumably be wobbly given that there is a toothbrush connected to your skull and its vibrating away like mad.
Does it also add the term "you're brushing it wrong" to the Apple list of reasons things don't work ?
First world problems that we can do without.
