IMHO, Next Generation of smart phones will be smart glasses.. May be 3-5 years out.. For now, I think just a matter of time before we see wider work related usage..
On next tech front, I am hoping to see display technology by MVIS to show up in popular phones.. 1st generation of this was out couple of years ago in small projectors but that is a niche market.. This Chinese company is the first one to do that ..
MVIS is worth a look and a position for what will be rolled out in next 18 months.. I am sure, I have probably mentioned this some where else before.. :o)
