I got my nook yesterday. I have a few books that I bought from B&N and I copied some of the epub books that I bought from Baen books on to the nook to see how things worked. As a point of reference, I have a Kindle 1 and a Sony PRS-505 in addition to the nook. I do most of my reading on the Sony.
I really can't tell much of a speed difference between the three units once the book is loaded and I'm turning from page to page. Starting the nook up from an off position rather than a screen saver position does take while, but then again, so does the Sony. Changing font sizes is much faster on the nook.
As far as I can tell, there just isn't a noticeable difference in the reading experience between the big 3 (Sony, Kindle and Nook). I think that the Sony is a bit more ergonomic than the nook, but the nook is more ergonomic than the kindle. I plan to take my nook with me to B&N this weekend to see what it's like in the store.
The big reason that my Sony will probably remain my main reading device is that it has a much better method of organizing my books. I like to have my entire library available to me (i.e. 1000+ e-books) and I like to organize the books that is in my to be read queue so I can access them easily (usually 20+).
My ideal would be to have my library on a memory chip and be able to copy books to the main memory of the e-reader as well as delete from the e-reader.
