I have a Nook Touch, that I rooted in order to be able to access Android.
The stock PDF reader is ok for reading a SR book from cover to cover. It has some layout issues, but other than that it let me read through Seattle 2072 correctly.
I also bought ezPDF reader, and it's far better at reading the PDF than any free reader. Don't expect to flip through the pages, though. It still takes too long to load a page for that. Thankfully, the index support is good enough to let you find the page you're looking for quickly. I don't know how well it works on more powerful tablets.
The drawback of the Nook Touch is that it's smaller than a Shadowrun book and when displaying the full page in the screen, reading is difficult. Zooming works, but I guess the experience would be better on a bigger screen.
The big advantages of the Nook Touch are that:
- It uses e-ink. So I can bring it for a complete gaming week-end without having to worry about having to charge it. And when reading a complete book, it's easy on the eyes. That's how I was able to read Seattle 2070 in the train/buses without having to carry a big book.
- It runs Android so I can do more than just read e-books. I can, for example, display James McMurray's GM screen
which is pretty convienient (and the e-ink allows me to have it at all time in front of me without having to wake the device from sleep mode).
I'm also working on a GM tool to help in combat, but due to the complexity of Shadowrun's system, it might take a while before it's ready.
- It's cheap ($150 or maybe just $100 now)
