If you buy the iPad, that and
iPieta will make it worthwhile because of the books on iPieta (in which I have no financial stake

) including the Scripture commentaries Haydock and Catena Aurea. Also has the Summa Theologica. Just getting those as books would cost more, but you also get the all Council (including V2) documents, Early Church Fathers, Papal writings from many Popes, several spiritual treasures like Introduction to the Devout Life, Story of a Soul…
Anyway, in addition, the iPad would allow you to download many, many books and articles in several formats, download MP3 talks (Check out Sonitus Sanctus for suggestions!) (and you don’t have to rely in iTunes for all this, get Downloads Manager (best for mp3) and Goodreader ( best for written stuff).
Radio apps as someone mentioned, Catholic radio, foreign language radio, Foreign Catholic radio… you can get one general app like Pandora or Tune-in for all of this.
I just have an iPod touch. I could have gotten an iPad mini, but I love carrying mine in my pocket and pulling it out wherever.
My son has an iPad mini and we found a case with keyboard included (under $50 at Amazon–don’t get an Apple one) which would have been fine for him as he is still small. My son at a liberal arts college says several of his friends have a full-size iPad as their main computer.
So, since you can get a Kindle app and have so much more with an iPod/iPad, I have to recommend the latter even tho I too am mad at Apple for what they did to BeamItDown… but I am also mad at Amazon for buying Stanza and destroying it so people tuink they have to rely on Kindle
ETA: Plus I have to add in Brevmeum, an old-breviary app onto which you can load several days’ worth of the Breviary.
