Not to worry. Most will be pleased.
The iphone 6 will be the same size or about the same size as the current iphone. No bezel and a bigger screen at almost the same phone size. My firm has it pegged at around 4.5 or 4.7. Hard to tell from their supply chain the exact size of the screen. But the phablet rumors are just that rumors.
People forget the fact that Apple promotes 'ease of use' in 'one handed use' they so famously remind us of. These mockups of a larger iphone 5 are ridiculous.
Now they have a prototype 'phablet' but that is just it, just a prototype. No analyst thinks they will release it. The ones who want to make a name for themselves will sell their soul to do so.
Anything is possible but our firm are not buying it.
