A while ago I grabbed some mathematics book samples for the Kindle. These were books produced by well-known publishing companies, retailing for considerable sums (even in the electronic versions), and in all of them the mathematics typesetting was atrocious. I think that in most (all?) ebook formats, a formula is included as an image, which means that it automatically resizes. This means that formulas may be of all different sized fonts, which gives the result a very scrappy look. At least PDF - even if not designed for ebook reading - provides decent layout.

Here's a post I wrote up once comparing a specific ePub display on a specific viewing program w/ a hand-tweaked Plain TeX version:

In the .pdf I believe there were only one or two places where I let two word stacks stand (because they were intractable) --- will have to try again using xetex and margin protrusion and character expansion (I'd used DEK's macro for hanging punctuation from _The TeXbook_).
