Why would you want it implantable? I mean, I get why, but at the speed the tech evolves do you want to cut yourself up just to implant something that will be obsolete in a few years?
Good point. I guess I want more stats with higher accuracy without having to wear something.
You could get a suppository device
Apple iPlug when?
Implant doesn't necessarily mean full on surgery under general anaesthesia, it can be as simple as a small incision with a scalpel and local anaesthetic.
Not everyone's cup of tea but not as dramatic as "cutting yourself up" either.
