I really wouldn't got for 6' screen for pdf. No matter how you look at reflow solutions, they will always be clunky. There will always be a picture too large, annotation too small and weirdly placed, that will make it a hassle.

For pdf you need something bigger. Ipads and similair lcds and M96, 912, and 8 inchers from Onxy and Pocketbook.

And don't think I didn't try them. I did read couple books on regular Kindle, I even manually cropped the books, and squized every millimeter out of the screen by modding the margins. PDFs are readable, but barely.
