It's not a matter of want, it's a matter of need. Nobody needs the stupid iwatch when the phone does the same thing. LoL.
Nobody, but a handful, needs to know their heart rate on a consistent basis moron. If you need it, it can be done like it has always been done - by taking your pulse. I'm in the health field. Too funny!
Interesting comment about graphite. I wonder what will happen first -aluminium replacing Lithium or silicone repacing graphite for batteries?
This article talks about Stanford already having a prototype using aluminum and all the benefits. Sounds like it's already here so...
But you said also that silicone is replacing graphite yet it isnt' true currently or for the near future. Why one and not the other? They're are in equal race to be replaced.
