[Blindtlk] i device questions

[Sarah]

good morning. I have an iPhone 4s that I really enjoy. I am considering purchasing an iPad. Is this a device anyone would recommend since I already have the iPhone? are there apps for the iPad that are not available for the iPhone? Would it be better  to have an iPad to take notes in a meeting or use in church? If I buy one, should I buy the new iPad mini or the older and larger one? I would like one I can easily take with me when I travel. I currently use a Bluetooth keyboard with my phone but am planning to purchase a Braille display. Thank you.
