"When the iPhone came out, nobody used touch devices... especially since most iPhone buyers were buying their first iPhone." Is iPhone already a synonym for smartphone?
He also disregards that touchscreen smartphones have been around since the 1990's and there were plenty of people outside the US who used such devices. If he mentioned that it could be used with just your finger, accurately, then he maybe right.
"But the biggest factor that changed the game were the concessions $Launch_carriers made to Apple." O2 made some pretty massive concessions in the UK too. Android came along and screwed that pooch well and truly! Don't get me wrong, there has been a lot of good that has come from Android, but handing the control back to carriers is harming consumers long term. Data limits are criminally low, and the reasoning behind them is based on fallacy.
