Hello,
I think if you have a choice I'd go with an IPAD over any of the others. B/C with an IPAD you have the best of 'all the worlds', so to speak. WIth the IPAd you can watch TV shows, on it, and still download and watch tutorials, and youtube videos for quilting as well as classes on quilting via CRAFTSY classes! You can also download books and read them from your IPAD. So to me, the IPAD would make the most sense for your craft room. I LOVE mine.
BTW: Congratulations on the 20yr anniversary at your job!
Let us know what you decide to pick!
