I wish they would do a bigger size kindle scribe. I read pdfs all day on my scribe, and often I wish the screen was bigger so the font size would be large.
Then don't. You can find flaws with any and every company, but it gets bizarre that such a nit-pick gets commented here every time that brand is mentioned. Most people don't care about GPL.
If you publish code openly for the world to use, it's not realistic that they'd respect any wishes or demands you make regarding that code. I can make an instructional video available to the public on how to chop wood more efficiently. If I demand that anybody who uses my technique only does it with birchwood, nobody is going to care.
The size is good for PDF reading, but PDFs with huge margins or small font sizes don’t work well.
One way to fix the margins issue is to use the “Send to Kindle” feature, which converts PDFs to the Print Replica format and trims their margins in the process. Sideloaded PDFs actually appear with more margins (thus reduced font sizes) than books sent through Amazon’s servers.
It works fine I would say. In the absence of a bigger screen with proportional DPI (kindle scribe is 300 which is one of the highest in terms of screen size), kindle scribe is one of the better options still IMO.
