How quickly we forget.
Since every phone has a touch screen these days it's easy to forget that before the iPhone was introduced, all phones had keypads.
The introduction of the iPad revolutionised the way people thought of tablets, devices which had been around for years. Apple got them right and now they're super popular.
In both cases, other manufacturers, even those who have been making products for years before Apple introduced their designs, have taken those designs and adopted them themselves. It makes me smile every time someone talks about how great the Samsung phones are nowadays. I wonder whether they'd be making such devices if the iPhone had never come out.
When it comes to televisions I expect the same sequence of events. First Apple will point out everything that's wrong with televisions, then say what would be great, "Wouldn't it be great if...". Then they will introduce a TV set which will revolutionise the industry.
And of course, a year later every other manufacturer will release TVs which copy all the ideas. It's happened before and it will happen again.
By the way, my predictions for Apple TV are; it will just be called "Apple TV" not "iTV". It will be available in three sizes with two models each for a total of six models. It will be no thicker than an iPad.
