Hi Denny,
As a 70+ year old I suggest you look at
http://www.ehow.com/how_2209407_check-e ... touch.html and its associated howtos on the side bar. You should have many test runs at home before you rely on this single very versatile device for communication. I am using this jack of all trades gadget for multiple things, such as a camera, maps, memo, alarm clock, showing family photos, Facebook, etc., also on Skype as a free international phone, and not only for music, you will learn as you go along.
The main difficulty is logging on into hotspots in unfamilar places. There are many many but some are difficult or tempermental to log on, try it out at the big Macs and Starbucks or at airports (usually OK) after seeting up your free accounts. Learn to tweak it, you can get all the tricks from your kids.
Enjoy
Grandpa Joe
