Honestly, there are only so many ways to design a smartphone with current mass-market technology and Apple are already pretty close to perfection.
- One thing that immediately comes to mind when looking at the 5 is how much wasted space there is at the front. I'd like them to shave off as much of the bezel as possible (while retaining the trademark home button and horizontal symmetry of the device) and squeeze in a nice 4.3 inch display without increasing the overall size of the device much, if at all.
- An all-metal back would be really nice.
- Might be a bit of a stretch, but this new
invisible glass technology could look amazing coupled with the iPhone's in-cell touch panel. It would greatly reduce glare and feel like you're literally touching what's on the display.
- Faster processor, better graphics, NFC, etc...
I think this would be a pretty nice upgrade.
