“Wouldn’t have one if they were giving them away”!
Well, you would be a member of a very small club. I think that perhaps you don't have much need to use a computer on the move, in which case the iPad's capabilities would hardly be in first gear. Your touch screen and your can't go with you on a train/bus or be carried around in one hand, and that's what the iPad is designed to do. If mobile computing isn't your thing you can certainly live without one.
If you do need computing power on the move the iPad is (still) far and away the finest tablet money can buy in what is now a huge market.
