Not exactly. And not the reason I own one.
I now own one for the same reason of easier portability. I used to go everywhere with my laptop, then (full sized) iPad and then.....
Do you see the trend?
I see lots of people who buy the cheaper low end tablets running to Apple in droves to by a an iPad mini for the same price. Add up all of the cheap Android tablets sold and I'd guess you'd have a user base of several million. Now would you but the Android or the iPad mini if they are the same price?
And I do agree with you about the portability.
