I just ordered a M92 -my first e-reader- and have no idea what you guys are talking about. But not being a nerd, now I fear my new gadget might not work properly out of the box when I receive it... and I will have to go through some fixing like you describe.
All I want to utilize it for is reading PDFs, maybe some E-Books, some WordPad documents I have written and might still write, and scribble annotations in them.
(I use Jarte (free version) which is WordPad with a spelling checker, word count, etc, but it saves as WordPad, not Jarte.)
Probably the first thing I'll read on it will be the Onyx M92 manual I downloaded here:
