The mainstream wanted a bigger iPhone when the 5S came out. Did apple deliver? NO.
The mainstream wanted a smaller iPad in 2010 and 2011. Android small tablets took off. Did Apple deliver? NO.
Apple did deliver when the tech was right. Remember those early Phablets by Samsung that had 3 hour battery life?
Apple never rushes hardware to the market. They would rather be a little late and offer a polished product than a little early an offer a turd.
