I will be VERY disappointed of Apple only has a 5.5 inch screen. I was hoping for a 5.7 - 6.0 inch screen.
Middle age people can't see the small screens and Zoom is annoying.
At least with a large 5.7 - 6.0 inch screen, I will be able to read my screen with 1 hand. Typing with 1 hand is NOT a requirement since I use 2 hands anyway.
The other disappointment will be a 1,800 mAh battery. I was hoping that a larger form factor iPhone 6 will allow for a 3,100+ mAh battery.
I hope that Apple does not come up SHORT on these 2 major features for an iPhone 6.
SIDE NOTE: A software switch to control the megapixel camera size would be great. In this way, the user can control photo and video size to some degree.
Can I be really greedy and hope for a removable memory card

Removeable flash memory is not rocket science technology.
