The thread you linked to has some very useful information, especially if it comes to choosing between Onyx M92 and Pocketbook 912, but it doesn't answer my main question: Is it possible to do this kind of reading/work using a 6 inch reader?
Simple answer, no!
While technically speaking you could use a 6 inch eink reader for PDFs, it is too small and slow for most documents. If you browse this forum or wait for more replies, you will see that what I am saying is the common case and answer for most Mobile read users that faced same dilemma before, including me.
I do understand your concern about tablets, but the true is that for PDFs, which is not an ebook format, 10 inches tablets is the best option. Not only because its size, but because the LCD technology is way more faster than regular eink devices., plus gives you color too.
I used to have a Kindle DXG, now forgotten by Amazon (no updates in more than a year) and jumping between chapters or going back and forth was painfully slow. I liked the size and weight a lot, but it was too slow. It also lacks of annotation features. iPad with GoodReader app, gives you all that and more.
Now, reading PDF o eink is doable, even on 6 inches, but unless the reader does landscape, it will be too small or you will find yourself zooming in and out a lot.
