1- I can't imagine not having one anymore.
2- you can have all your quilting magazines in a reader program--I use the Kindle ap.
3- download every free pattern you can find and read in Kindle ap as above.
4- read regular books and such... I have read 2this week.
5- watch tutorials right at your sewing machine-- starting and stopping as many times as you like.
6- email...
7- camera...
8- FaceTime (it's a videophone ap)
9- it's fun
10- stream movies ( Netflix)
and that's just off the top of my head!
i don't go anywhere without it.
