theres no need for you to act like such a condescending know it all. i have several high end watches and i assure you, the apple watch is fat and ugly and will be much thinner in the coming years, one would have to be pretty daft not to realize that.
im not sure why the fact there isnt any spare room in the current watch means they wont be able to slim things down in the future. obviously its as thin as they can get it - today. "no spare space" in the watch is different from any old fat apple product how? im sorry but there was no spare room in the iphone 3g either, but technological developments allowed the phone to get to less than half of that thickness in about a six year time frame.
youre also admitting that what i want is possible with advanced screen tech.
you then contradict yourself and concede that while screen tech would get us there, you turn around and say its impossible to have good battery life and thinness. i guess its good (and obvious) that you dont work for apple. apple will surely prove you wrong in the next few years.
you also say that theres no tech in the pipeline to increase the density and consider a 30% increase "generous". youre wrong here too. why dont you google SiNode Systems (a successful startup started by a college lab partner of mine
www.sinodesystems.com) and read the very homepage, they have already developed graphene batteries that yield 200-700% more density than a typical lithium ion battery, forget your "generous" 30%.
before acting like a condescending know it all who can see into the future of technology, you should probably educate yourself on current technological developments. seems like you are devoid of a technical background, given your posts trying to sound authoritative on a subject you dont seem to actually know much about.
