Apple better have gotten it right with the iPhone this time around if they're this close to production.
That means they need to add more file space, more system memory, an even higher resolution screen and better battery life.
If not.. they're gonna fail, hard. Apple has had plenty of time to listen and study the success and shortcomings of the iPhone for a while now.
Like many manufacturers Apple makes money selling hardware. The amount of real changes to iPhone will trickle in year after year. This causes the masses to want to upgrade. I still have my original model because I thought the improvements weren't enough to switch. By the time the next model comes out I will be ready.
