This video gives you a deeper dive into the Kindle Scribe. What it does not mention is how the larger screen lets you comfortably read PDF files and the fact that you can in fact draw and write on them.
If that is not your cup of tea and you just want a premium reading experience when reading books you bought on Amazon, I still recommend the Kindle Oasis and as a budget option the regular Kindle. Many years ago I bought the second-generation Kindle because English language books were so much cheaper, and it paid for itself in months.
