Which Kindle should I buy?

I agree with the others. Don't get a tablet, the usp of a kindle is that it isn't like reading a screen.
I've read ebooks since I started on my palm & the best by far is my current oasis which sadly has
a rapidly failing (battery). I love it & have no idea what yo replace it with. I've looked at the scribe but I think it's going to be too big to read on, and possibly too heavy so I'm probably going to go with the paper white - I'm not sure colour would enhance my reading experience. What I'm really really going to miss is physical page turn buttons.
Like toastofthetown I'm pretty tied into the Amazon ecosystem but if you are just starting out some of the others might be worth a look.

You can borrow books from the library using Libby I think. I've never bothered, because it is a little convoluted, but it can be done with a pc and a wire!

I agree with others. The paper white.

Don't get a fire, that's a tablet, you may as well use the tech you already have if you get one of these.

I'd be wary with the new Paperwhites (12th Generation), because there have been numerous reports of yellow banding on the screen. This also affected the new Colorsoft but I believe the issue has been fixed, but there's still the risk of having old stock shipped. Amazon have a good returns policy though, so if you do have a faulty product, it should be easy to return.

• All new Kindles have lighting built in, the same screen resolution and USB-C charging. The basic Kindle is the smallest (6 inch), which isn't necessarily a drawback if portability is important to you. My beloved 2011 Kindle is a six inch screen and personally that's the perfect size for me because I can take it anywhere.

• Next level up, the Paperwhite has a 7 inch screen, the option to change the tone of the lighting from cool to warm and is waterproof.

• The Paperwhite SE also has automatically adjusting lighting and the ability for wireless charging.

• Then the Colorsoft has a colour screen, but nothing else the SE doesn't have. Probably not important unless you're reading graphic novel or comics, because most books are black and white other than covers anyway.

• Then the Scribe is larger again (10 inches) and as the name suggest you can write on it. It doesn't have wireless charging.

The other spanner in the works is also considering a Kobo. I'm fully tied into Kindle now, but Kobo has just as large a library (unless you're interested in something like Kindle Unlimited which does have many exclusives, but I'm not), you actually own your books unlike Amazon where if they close your account you lose your library, and the ability to rent library books which isn't possible on Kindle UK. I've never used a Kobo though, so don't know how the UI compares.

Edit: I also wouldn't get a Fire tablet for reading. The beauty of a kindle for me is that it's not a backlit screen and is a dedicated device for reading on without distractions. I use the Kindle app on my phone if I don't have my Kindle with me, but for me the experience is nowhere near as good.

I have a paperwhite and love it. It's one of my prized possessions 😂

If you are wanting an e-book, I would go for the basic or the paperwhite. I wouldn't get a Fire if it's primarily for reading - you may as well read on your phone using the kindle app.

I have the max 11 fire and I love it. The battery lasts ages and I use it to watch Netflix etc in bed or when away when needed as well

I don't have any social media apps or emails on there so no distractions.

I have recently got one and went for the paperwhite. For me it was the slightly bigger size which made the difference.

I have a paperwhite. It's backlit so you don't need a light on to read at night.
