Why I have it: Light, portable, and PERFECT for learning languages.
One of my favorite pieces of gear is my kindle. Before getting this guy I would carry around 2-3 books, each book taking up more than twice as much space as the kindle itself.
The other huge positive is they have backlights in the kindle. I use this aaaaaaall the time at hostels and while in airplanes. Then I can read any time of day or night and not bother my fellow hostel goers or airplane riders.
The main reason I decided to ultimately make the plunge is because I was trying to learn Spanish and if you download a dictionary and a foreign book you can instantly get definitions of words by just holding your thumb on the word. I cannot stress how helpful this has been for expanding my vocabulary in both Spanish and Portuguese.
I have owned a Kindle Paperwhite Ver 2 and the newest version from 2022. Some of the benefits of the newer model: USB-C, waterproof, warm light background, and a much quicker page flip. But any model will do! You could get a used Ver 2 on ebay and do tons of great reading on there!
