I'm slightly baffled....
....what did I say, mixture?
In the original post I thought it was apparent that it it is my wife who is pondering buying an e-reader. And on 9/10 hour flights, yes, she does just want to read books and this is a lighter way of carrying a fair few books rather than the traditional version.
All I said was that, at home, I already have a PC and a laptop and that I saw no need for anther expensive piece of kit.
It was originally just a simple question. I don't need admonitions about "doing my homework".
I'll leave it there.
