Portable device technology has reached a temporary apex. This could last another 2 to 5 years. It's going to be the same deal, lighter, thinner, different colors.
The next thing is going to be flexible devises that make your phone even more portable. This is going to take some time.
For those wanting new Apple innovation, you have to accept that fact that we are just now starting to experience the apex ceiling.
I for one, am amazed at what I have right now. Regardless of whether the innovation has been incremental year over year, the power of a cell phone, a tablet, a laptop, is exciting. The capabilities are endless. Instead of complaining about a lack of innovation, I'm still in pursuit of getting the most out of the technology today, and I have a long way to do. Be creative people! You make the machine, the machine doesn't make you.
