Negatives
* Does nothing for annotating PDFs vs other platforms.
* Doesn't always work properly
* Adds having to use WiFi/Internet twice or four times!
* Poorer for environment
* Gives Amazon a copy.
Positives
* Allows annotation on Kindle Scribe (no other Win/Mac/Linux/ Android/iOS annotation program or ereader needs a "cloud" connection or conversion).
What other benefit has it?
PDF margins can be cropped, OCR layers can be extracted, image based PDFs can be reduced in size... A wide variety of tools and some ereaders & apps & programs have them built in.
PDFs are especially designed for a particular page size at format/design time and to be viewed or printed. It's one of the worst formats to convert. The only successful Amazon "conversions" simply add a wrapper of Amazon DRM with the actual PDF inside.
The way the Amazon and the Scribe use PDFs (misuse) is an attempt to take control, have your documents and create a walled garden, It's worse than Sony DPT or the reMarkable.
Okular is one of the best PDF programs on Linux. Summatra on Windows. Pocketbook App (reading) on Android and Nebo is best for annotation on iOS & Android.
The PDF native reader on Elipsa (crop built in now), Sony DPT and reMarkable allow annotation and that adds a layer that can extracted. They do not require an Internet connection or someone else's server (that's what the Cloud is).
However I've found that 14" is a minimum size to read all PDFs. The Scribe isn't big enough for many and the Elipsa and reMarkable are slightly poorer resolution. The colour Onyx 10″ is much poorer resolution and very dark.
