Previously, I mentioned that Tony had learned to say "Dad! I need to check my email!" when he wanted to get on my laptop and play with the Microsoft Train Simulator program.
He learned this when I kept asking him if I could check my email when he was playing with the trains.
Just now, as Tony was playing on my laptop, I decided to play with the Ipad. I did this for about fifteen minutes before Tony noticed.
All of sudden, Tony grabbed the Ipad from me, and said "Daddy! you can check your email!"
It seems he prefers the Ipad.
