Thanks April, The books I want will be expensive and I want to be sure that I don't loose them because of an error I make. I met a woman at McD's who was using an Ipad and recommended it. She said when she downloads a book it goes to her kindle and her ipad and even saves the book mark on both. Sounded good. I will keep your offer in mind. I bought the Ipad for dummies because it is easier to read instruction while trying it on a device.
I have the kindle app on my iPad, and also a Kindle Fire that I use for reading books. The iPad was fine for reading, but then I got an external bluetooth keyboard case to make typing easier, (which it did) but it made it harder to just sit and read a book.
When I get a book from the Kindle store, it asks me where I want to download it to, but I can read any of the books on either device.
The only ones that I can't read on either device are ebooks that I borrow from the Kindle Lending Library. You can only use an actual Kindle when borrowing a book; but when you purchase a book, you can read it anywhere that has a kindle app on it.
A good way to get familiar with the Kindle procedure would be to get 1-2 of the free kindle books and download those. Once you have done that, you can see where they will go, and how to find the books on both of your devices.
After you are familiar with the book-buying process; then you can start buying the expensive books that you want.
Personal opinion: I would think that the iPad Mini would be easier for reading a book than the regular iPad, since it is smaller and easier to hold when you are reading.
To sync, just turn on iTunes on your computer, and connect the iPad to the computer with a usb cable (that you use to charge the iPad), and it will find your device and sync it. Then do the same thing with the iPad Mini. However, you should not have to sync to get the books on both devices, because they will be in the cloud, and can be accessed from either device.
