>I would never have bought it myself since it costs €249 (!)

I bought my Oasis 2 around for closet to 299 EUR (309.97 USD) when I was making 30k USD a year, was 100% worth it to me while I still had a fully functional kindle keyboard and kindle paperwhite 3. If you're a casual reader, that might seem expensive, but if you are chewing through 1-3 books a week like I do (heck I read 3 books last time I flew from Indianapolis to San Francisco and 2 more on the return flights), it becomes a much better price.

I've been using it for almost 5 years now which has me at a cost of 17 cents per day with thousands of hours of use (about 8 cents an hour if I had to guess).
