I just posted part 2 of the review over on my blog. I think it's worth a read.

Original Firmware

When using the default firmware (v1.7), the N516 scores a 1 out of 3. It has no sleep mode, and it can’t read a popular format. In fact, it’s really not very good at reading ebooks. My unit only supported HTML, TXT, and PDF. The HTML was completely unusable; all of the tags were ignored. The PDF was marginal (on a 5″ screen). And the txt is text.

Open Inkpot Firmware

My reading experience improved greatly after I installed OI. Open Inkpot uses FBReader as its reading software, and all of FBReader’s features were implemented: page margin, line spacing, font choice & size, justification, everything. It’s difficult to convey how many options FBreader has, but I can say that it will satisfy the pickiest user.

My Recommendation

I still think the Jetbook is better, but if you get the N516 then you should install Open Inkpot. It’s worth it. If it were available, I’d use the OI firmware on my Jetbook.

I'm still trying to find the right level of detail to include in a review. If there is too much detail, then the review is too long. Too little detail, and it's shallow. I think this review is about right. If you think there's something I missed, please let me know.
