Old Kobos were awesome, I had one for years running Kohreader. Sadly I lost it. Then when I researched new Kobos, about two years ago, it seemed like the quality has gone down a lot as the company has been sold several times. Is that still the case?
Inside is a micro SD card so if I ever need more storage I can just clone the original SD and extend the partition to upgrade the storage.
The Kobo are so much better than the kindle imho: more open, not locked down, and the typesetting engine is Mike’s ahead: no ragged edges or page long rivers unlike I was getting on the kindle.
