Why choose the iPad for a senior?

I've used Windows and Mac computers. I have a Kindle and an iPhone. Video games at my house include an Xbox 360, a Wii and Wii Fit and Nintendo DS handheld games. So, why did I choose an iPad for my  80 plus year old Mom?

1. It's much lighter than a laptop. She'll be able to put it in her walker pouch and take it with her from room to room if she chooses.
2. It can operate longer on a charge than a laptop
3. It doesn't need a nite light like the Kindle. I love my Kindle, but this is a different situation.
4. It does far more than the Kindle does, via Apps.
5. My Mother understood my iPhone screen and how to slide to more photos almost immediately.
6. My Mother likes hand held games including casino games (poker, slots), hangman, word games and Yahtzee.  Most of these are available for the iPad.
7. I've shown Mom the iPhone Yahtzee app - she took to it quickly.
8. There's no On/Off confusion. simply push ONE BUTTON. Windows laptops are very different - click START to turn off (WHY?!?!) then choose Sleep, Restart, Shut Sown or Hibernate. Argh!
9. The iOS update includes text size adjust settings.
10. I've used an iPhone3gs for a year. I think she'll take to this.
11. There is already  wireless (WiFi) at her home.
12. She didn't take to the DS screen, I think it is too small for her.
