Then one day I saw a stock clearance offer and bought an Ipad because the price was so good it was a steal.
Then another day I added three pdf books to ibooks so I could read it on vacations, then three more, then ten, then twenty.
I also use it for note taking and sketches. The pencil and the ipad is an old model now but I love it.
Then I stated using it for programming with my own side loaded apps that connect with a big computer.
Then for minor things like controlling my 3D printers, for showing something to someone(work colleagues) you can do it while walking which is very useful.
So the thing only does three things for me, but in those things the thing is essential.
