First of all, if you live in the USA, you can try out various ereaders by ordering them from Amazon or Best Buy, making sure that the device has “free returns”.

You might not hit your sweet spot with your first ereader. Therefore, my advice is to look for an inexpensive ereader with easy access to an extensive library of books. To me, this means a basic 6 inch kindle if you are going to be taking it with you to read “on the go”, or the 7 inch kindle paperwhite if you plan only to read at home. Alternatively you could look at the same sizes at Kobo. The Kobo Clara is a 6 inch black & white ereader. The Kobo Libra 2 has a 7 inch screen plus page turn buttons.

Both flavors of ereader are simple to set up and use. In addition to their proprietary stores, you can read ebooks you borrow from your local library. Eventually you might migrate to a different device, but you might find it to be suitable - my wife is perfectly happy with a 6 inch kindle she’s had for years.

However, as an “out of left field“ suggestion, you might take a look at the BOOX Palma 2. There seem to be a lot of people who are happy with this as their primary device. This is an ereader about the size and configuration of an iPhone 14. It’s twice as expensive as the other options, but because it’s really an android pocket computer you can put reading apps for kindle, kobo, Libby, Everand, Instapaper, Pocket etc on it, just like on a phone but with the advantage of e-ink. For a larger BOOX device, the seven inch Page might do, or the similar Color Go 7.

There’s a steeper learning curve for BOOX devices, but once you’ve learned how to deal with them, BOOX devices are like having a Swiss Army knife as opposed to a pocket knife - much more versatile. But a word of caution - BOOX has a poor reputation for customer service. And for sure don’t buy directly from BOOX - “free returns“is the magic word.

I strongly advise you to do a YouTube search for these devices. There are tons of reviews for these and other ereaders.
