Quick answer: if you read more than a few books a year, yes. An e-reader is easier on the eyes than a phone, the battery lasts weeks, and the devices themselves run for a decade. The part most buying guides skip is the money trick: at participating US libraries, a free library card plus the Libby app makes most of your reading cost nothing. The one honest fork in the road is Kindle versus Kobo, which is really a question about how you feel about being locked into Amazon.
The e-reader debates across r/Frugal, r/BuyItForLife, and r/AskReddit include one thread literally titled “Kindle Paperwhite: do I need to be deinfluenced?” The answer the thread gave, by a wide margin: no. But the dissent in that thread is worth hearing too, and we’ll get to it.
The case for buying one
Three things come up over and over. First, your eyes. The top answer in the deinfluence thread, with nearly a thousand upvotes: “Get the Paperwhite. Much easier on the eyes than phone or iPad. Cheaper than iPad, too. Worth every penny.” Second, reading volume. One owner bought theirs right before lockdown and has “read over 100 books per year since getting it.” Removing the friction turns out to be the whole product.
Third, these things refuse to die. There’s a whole BuyItForLife thread celebrating a 10-year-old Paperwhite, where another owner adds: “I still have a Kindle Voyage from 2014 and I’ve only ever had to replace the battery. Low power electronics can easily last a lifetime.” One buyer did the long-term math: a $120 Kindle twelve years ago, still the rough price of one today, and years of paper-book savings on top. Amortized over a decade of reading, the device cost rounds toward zero.
The money trick: your library card
Here’s the section other Kindle reviews leave out, and it’s the strongest argument in our whole dataset. You do not have to buy books. At participating US libraries, a free card plus the Libby app lets you borrow ebooks straight to your Kindle (Libby’s Kindle delivery is a US-library feature), and the r/Frugal crowd treats this as the default way to read. One owner uses their “digital library weekly if not daily.”
The dedicated readers go further. In a subscriptions thread, the top answer with over 2,500 upvotes was a non-resident library card: some big library systems let anyone in the country join for a small annual fee, which buys access to a much deeper ebook catalog. Around $50 a year in that comment, though programs and prices change, so check a library’s current terms. For owned files, people have used the free Calibre app for over a decade to organize and convert their own books. The e-reader is a one-time cost. The reading can be free forever.
The honest fork: Kindle or Kobo
Now the dissent, because it’s legitimate. The strongest counterargument in the deinfluence thread wasn’t about the hardware at all: “I will try to deinfluence you just because it’s an Amazon product… there are similar products like a Kobo where you have a lot more capability to actually own the books and aren’t locked into the Amazon ecosystem.”
Two facts back that up. Amazon eventually ends store connectivity for old devices (books already on the device keep working, but store access and new delivery go away), and one owner switched after their “10 yr old Kindle was no longer being supported.” And Kobo has a feature Kindle owners envy: built-in Libby borrowing on supported devices, availability depending on your library. As one r/Frugal commenter put it: “Kobo integrates with Libby!! Buy the Kobo, never have to buy a book if you don’t want to.”
The fair summary: Kindle has the bigger ecosystem, the easiest buying experience, and Kindle Unlimited if you want it. Kobo borrows library books more smoothly on supported models and is less tied to Amazon, though Kobo Store purchases can carry DRM too; the real ownership edge is sideloading open formats. Both last a decade. You’re choosing a bookstore, not a gadget.
Buy it or skip it
Buy one if you read, or want to read, more than a handful of books a year. The eye comfort is immediate, the battery is measured in weeks, the device outlives most laptops, and with a library card the running cost is close to zero. Few purchases on this site have this good a cost-per-use story.
Skip it if you read a couple of books a year and your phone doesn’t bother you, or if most of your reading is PDFs and textbooks, which e-ink handles poorly. And if the Amazon lock-in argument resonated with you, that’s not a reason to skip an e-reader. It’s a reason to buy the Kobo.
FAQ
Is a Kindle worth it if I already read on my phone? That’s the exact upgrade most owners describe. E-ink is dramatically easier on the eyes, there are no notifications, and the battery lasts weeks. The people who read 50-plus books a year on one almost all started as phone readers.
How do I read for free on a Kindle? A library card plus the Libby app, at participating US libraries. Borrowed ebooks deliver straight to the device. If your local catalog is thin, several large US library systems sell non-resident cards for a small annual fee with much deeper collections.
Kindle or Kobo? Kindle for the biggest store and the smoothest experience inside Amazon’s world. Kobo for built-in Libby borrowing (device and library permitting) and easier ownership of sideloaded, open-format books. Owners report both lasting 10 years, so pick based on where you want your library to live.
