Kindle DX - is for sure the device with very limited features. But its eInk screen is much more comfortable for my eyes than JBC's one and it is much faster as well. DX doesn't have many features in its specifications. But everything it has in its advertised product specifications is working PERFECTLY starting with the picture of the DX (
http://www.amazon.com/Kindle-DX-Wire...2026898&sr=8-1 ) where it looks exactly like in real life and ending with 3G radio which also works perfect and is a very convenient feature for our family. And $199.99 (the price I paid for my DX) is a fair price for it.
But I also wouldn't trade JBC for second DX because I want eInk 9.7" with more features than DX can offer - mainly more book formats, more languages, dictionaries and SD card can be useful, too with about the same quality of eInk screen as DX offers. Also this trade wouldn't be fair in $$ meaning $199.99 (DX) vs $499.99 (JBC).
I mentioned in my first post that the ideal Reader for me would be something like Sony T1 with addition of some community developped tools (which I found on this forum) , but with 9.7" eInk screen instead of 6". Unfortunately Sony doesn't make 9.7" eReader. So since I have to choose from what is currently available on the market, then I would trade JBC for Onyx M92.
So if somebody wants to trade his Onyx M92 for JBC I will be more than happy to do this. But I doubt if any M92's owner will be willing to do this.
