It's a convenient size. Actually, a fair few have 5" screens as well these days. Smaller readers for novel reading... sure, they're going to typically munge technical books and the like horribly, but they're not really intended for such!
Well, it's not altogether out of the question for especially sized PDFs are made for them. I made an iPhone sized version of Intro. to Mathematical Philosophy, which is somewhat technical, and the iPhone screen is even smaller than the 5" screen.

Agreed. In the meantime, though, if you want to stick with HTML or XML source, and want pretty good looking output -- not quite as nice a LaTeX in my opinion, but pretty good -- you could try converting to PDF via Prince XML. It uses even uses TeX's hyphenation algorithm, and has some other nice features we've been praising TeX for, despite using XML source It also has *some* support from MathML, though I don't think it's comprehensive. (Haven't tested that yet.)

I've started a thread about Prince XML here with some screenshots comparing to those I already posted in this thread for ADE's ePub vs. LaTeX.

Doesn't XHTML already "support" it?

Actually, I was trying to imply that I expect adobe to support MathML the same way that browsers support it: techically, if even that, but practically either not at all or not well.

It's not in the current ePuB standard. It looks almost certain it will be in the next revision.

One of the thing that need to be added to epub is a better support for tables and images.

I have an ePub from o'reilly, it's a bit of a mess with that when image or table or larger than sceen. I like the o'reilly way. You pay, and you can download mobi or ePub or pdf, drm free, anytime you want. That's the way it shoud be everywhere.

I do not believe this is an ePUB format problem but a problem in the rendering software/firmware.

One trick mobi does in some implementations, that I like, is to use the next page button a bit different on a too wide table. Instead of going to the next page it shifts the table to the left thereby letting you view the part of the table that was cut off. These is an almost transparent intuitive solution that works pretty well for most tables. Hitting the previous page button while scrolled over will scroll back.

Many readers have a special view mode for images that allow independent zoom and pan of the image.

I just took 8" as a guideline, I figured the 6" people will have to scale down. There's only so much you can minimize the pages of technical documentation before it starts to get almost impossible to get good looking pages.

Also, it's not just the layout I made different. Apart from minor text changes ("the graph above" versus "the graph on the next page") which could be automated, there's also the fact that e-readers offer functionality real books don't. For example, you can zoom in! My book happens to have an illustration of the Mandelbrot set, and in the ebook version I added some text to encourage the reader to zoom in on the set.

In principle, ebooks could be much more interactive too. Imagine a math tutorial where you could edit parameters of graphs and have them regenerated on the fly!

The problem is there aren't many implementations of viewing mathml --- opensource.adobe.com actually uses .gif images (w/ the LaTeX source code as the alt text) for any equations.

Oh, but there will be for ePub. After all... it's ePub. EPUB!!!



But, to be serious, yes, your point was basically my point. MathML becoming an ePub standard should only make those weary of life hold their breaths for quality mathematics support.

Some PDF viewers now do that, e.g. Good Reader from goodiware.

Well, if you have a very technical book with graphs, figures, tables,charts on virtually every page, you will find there's NO format in the world that is an ebook format, for the 6-'' sized ebook readers.

PDF is an excellent format to present technical documents/books with large portion of non-text content, I doubt if there was any better format available.

ebook itself is not necessarily for reading devices, for a very long time people read ebooks on their computer screen. So ebook format is not necessarily the format for ebook reading device.

So PDF is definitely an excellent ebook format, though not a good format in case of book with graphs/charts/tables for 6-'' sized ebook reading devices (Dude, is there any format could do that better than PDF? I don't think so).

You can have a technical book like that, it just has to be designed for that size --- one of our customers for a long publishes a medical reference book w/ a number of tables and figures in a small 4 x 6 in. format which is quite readable on my PRS-505.

using a pocket pro I haven't really had much of an issue so far with pdf- so long as I set the text to medium it gives me a full page preview and then reflows the text on the next page - one plus about having pdf is that it is pretty universal if you need to hand it off to someone w/o ebook reading capabilities- I mean if I wanted to say, read something on my reader and needed to send it to my mom if I sent her a .lit or a .pub or even a .doc she would prolly have troubles opening on her computer it up but she would be able to open a pdf
