I have an original eink kindle with wifi and free 3g and still use it but they don't make those anymore. These days I use the kindle app on my Samsung 10 inch tablet. I have unlimited mobile hotspot on my phone so can connect the tablet that way if I need to download a book while traveling. Mostly every where you go these days there is free wifi available. I ditched my kindle tablet years ago. Had the defective model with the charging port issues. Amazon replaced it 4 times but I had enough and found regular tablets far superior. I would just get a good e-ink kindle with wifi for him. If he reads a lot the oasis is very nice and you can get it in a 32GB model to hold a lot of books. I played with the 2 at best buy a few months ago and thought the voyage very nice even though it was pricey. Mary

I thought the average Kindle-version ebook file was in the 1-2 MB range in size. Call it 2 MB. 1 GB would hold 500 books. If the average book is in a smaller file (which I think they are), then it's even more than 500 for each 1 GB. I can't imagine anyone could possibly need or be able to make use of anything larger than a basic model (8GB?).

It's not necessary to have all of one's previously purchased or otherwise obtained Kindle books downloaded on the device at any one time. Books obtained are held online by Amazon and are always available to be downloaded at any time.

No clue but initial phone and tablet stuff always take up part of storage so you loose some I would think even with the oasis and voyage. I have a memory card in my tablet and all my books are on there.

"No clue"

Then why did you make the recommendation?

No "phone and tablet" stuff on a Kindle. If your own ebooks copies are purchased, why the need for a memory card in a tablet? Same thing, they take up little room. Why do you find a need to continue to keep on board books you already read? Keep them elsewhere, load them on if you decide to read them again some time.

I'm not into tablets or e-books, but I thought the advantage of the PaperWhite is that it takes no power for the display, it only uses power when downloading a book or change pages. Is this feature available on any other Kindle device? My wife reads a lot of books on her iPhone, downloaded from the library.

mtvhike, I think one of the advantages of the Paperwhite models is that they're easy to use in most light conditions, including in bright daylight. I don't know about when it does or doesn't use power but I think most Kindles are known to be useable for a surprisingly long time, hours and hours, before needing recharging. Maybe others could comment.

I have the 2018 10th Gen paperwhite and I am almost sure it has Wi-Fi . I don't use it so I am not positive
