I have moved various PDF files to Kindle, and I never had any problems with it. Just use the USB lead you get with the kindle, and drag and drop the file into Docs or Books file. The main problem is the size of the screen in my opinion. I mainly used them for reading when out and about,and displaying NPC portraits at the table. Now though I use a tablet type laptop, and moving more towards remote play, so they dont get used quite so often.
