Why You Can't Build a Smartphone
Sorry, but you don't seem to be offering anything new here.  We know there are large capital costs for hardware businesses.  We know network effects exist for phone applications.  We know UI performance is a key issue in smartphone adoption (currently).Maybe "It's Hard To Build A Smartphone In 2013" would be a better title.  But to suggest people will be using iPhones and Androids in the year 2050...Yikes.  I pray that future doesn't come to pass.
