So I felt like some variety last night, and went into eReader to choose from a much larger selection than I currently have in epub, but I couldn't make myself read with it. All that bright white light pouring off the lettering from the top and bottom winmo bars alone was enough to make it miserable. My color scheme in Freda is just right -- the best reading experience I've had since I used my old monochrome Palm m500, and I really have no desire to undo that.
Full screen reading probably sounds like a small feature to some people (like, for example, fictionwise), but to me it's a huge deal -- and since I'm the one doing the reading, my opinion is the only one I care about.
So now I'm trying to convert some of my old standbys to epub so I can increase my Freda-compatible selection. Hopefully it's easier than it looks.
