Should I quote myself with emphasis? "a tablet product is no more A SOLUTION TO ALL THE PROBLEMS faced in this market than a car is as a mode of transport"
Let's look at it backwards.... That means that you can't solve all your transport issues with a car. You can't cross the atlantic with a car. You can't do a red-eye drive from Vegas to New York in a day driving a car. You won't be driving a car across a foot bridge, nor inside a building of through a path in a park. You won't be driving 20 people in a car, nor will you drive one if you need to entertain at the same time.
Now... On the same vein, a tablet, any tablet, is not the be-all and end-all of control nor input. We're at a different stage of the game, but look how well the Pronto line of products did compared to their competitors. And it wasn't because of marketing.
I maintain that you either actually haven't understood what I've written in a few messages or are being disingenuous.
