I bought a colour Kobo. Super responsive by comparison. The colour isn't wonderful, I like that it's there.
Also, physical buttons! Such things are only available on the most expensive Kindle, I didn't realize how much I'd missed them.
Or the old ones you can get for $10 on eBay :) I use exclusively old models that have physical buttons for Kindles because they're just insanely cheap and still perfectly reliable (the battery too) even a decade later.
I went through a phase of buying used 4th gen ones off ebay so that I could have physical buttons to turn the page, but within a couple of months they would always end up up with cracked screens
They would be stored in my bag next to my laptop (and in a case) but at some point I would end up pulling it out to read and find a cracked screen
I think I went through 4 of them before I called it quits, my current paperwhite is still going strong (just no buttons sadly)
