The next step for Apple
With the launch of the iPhone Apple changed the world of computing forever. Since then Apple has fought a war against Samsung, Google and others over the dominance of the mobile market. But not a lot has really changed. 
Apple introduced the high pixel density display, Samsung launched larger displays. All the companies have introduced all sorts of bells and whistles to try to catch the interest of the consumer, but to little real effect. The basic model hasn’t changed all that much from the original iPhone.
Many people are thinking about and desperately trying to predict the next step. Google is launching Glass, a smartphone-like display that sits in the corner of your eye and is controlled by your voice. Most companies are working on watch-like devices based on the rumour that Apple is making one.
That got me thinking, this is an odd assumption. Why should reinventing the market require a new device? The iPhone was certainly not the first phone, nor smartphone. It was just radically smarter then the competition. Instead of launching a new type of device, what if Apple would drastically improve the devices they already have? What could they do?
The next generation: Real Touch
The central feature of the iPhone, and the iPad, is the screen. When Apple added the Retina screen the other companies scoffed and smirked claiming it would only decrease battery life. But after they got their hands on it, the entire market rapidly went with high pixel density displays.
What if Apple would add high density touch displays next? You can still use your finger as a primary pointing device. But also a stylus without lag or stutter. Maybe several people could draw and sketch together on an iPad.
The scoffs and smirks
Very few people will read this and go “wow! What an amazing and novel idea!“. Most will remember the failed styluses of yester-year and think I’ve fallen off the wagon. But what if, just like with the retina screen, there would be no down side to these screens? What if they simple worked as magic paper?
Wacom has the technology already. Now it is just a question of price and if Apple believes the market wants this. I say Apple, because even if Samsung and Microsoft could also do this I think their implementation of it would be lacking.
