I recently got a Sony PRS-300 (the Pocket Edition) after having used a checked-out-from-the-library PRS-505 for awhile. The reason I prefer the RTF format is that it makes it easy for me to go in and change the font size in the file to better suit the PRS-300. The standard Arial 20pt. used in the archive's RTF files is perfect for the 505, but appears too large on the 300. I go in and reduce the font size to 18pt. for my reader once I've dl'd the file. I don't know if there's a way to do that in the ePUB format, but I should probably find out. Also, RTF doesn't seem to have some of the formatting issues I've seen with other formats.

Found through metafandom. I really love the archive, btw, because I only have internet access at work, and it makes saving stories to read later so much easier than copy/pasting each chapter into a Word document.

Thanks for the suggestion about editing epubs. I'm still kinda new to this, and still learning.

I'm glad you still provide RTF, even if it's a hog, because I find it the simplest format to edit myself, and as I later read in comments, because apparently others do the same things I do and edit out misspelled words when they find them. I miss having the art, but reading fluidly wins out.

I'm guessing a lot more people still have 500/505s than 300s, so I think the formatting you use is probably the best for the largest number of people. I would have purchased a 505 for its larger screen and better placed page turner if they were still on the market, but when I found a 300 on sale for $155, I snapped it up. And I didn't really want all the bells and whistles of the later models (touch screen, web services). I use it pretty much exclusively for fanfic and occasionally to read articles that would chain me to my desktop computer otherwise.
