But for being just an eink reader, Kindle 3 and Kindle DXG do a decent job, better than the Nook classic and Nook Touch. The landscape mode and the zoom, helps a lot, both features absent from Nook.
The Sony has better PDF capabilities than Kindle 3 but again, 6 inches is too small in my opinion for a PDF, that's why I still prefer an iPad for that, plus is lots of times faster turning pages and jumping among chapters.
