And I've been wary about publishing them :)

Shameless plug: I put out jsmag in PDF, and regularly get people asking for Kindle version, but have not yet been able to make something look decent. Revisiting this again next month. Suggestions/guidance on this topic welcome.

I had good luck with formatting things for my Kindle with LaTeX. I just set the page size to be proportionate to the Kindle screen and compiled a PDF. The result was far better looking than using the normal Kindle format and I didn't have the normal issues with PDFs because mine actually fit on the screen.

This wasn't the most space efficient system, but it was probably the best one aesthetically. Also, since I just created a custom .sty file to automate this, I can have my single source document output both normal-sized and Kindle-sized PDFs.

interesting - thanks.

I read almost all of my technical books (I've stopped buying technical paperbacks a couple of years ago) on iPad. For whatever reason (natural born cyborg?) my eyes appreciate glowing screen. If only I can make iPad lighter...

I think Kindle DX users will benefit from the kindle edition. Technical books is a pleasure to read on a Kindle DX.

DX's a bit expensive, my compromise is to read in landscape format on my standard size kindle.

Yeah, I couldn't afford a DX. I end up reading the "content" on my Kindle and when there are long code snippets, I read it on my Mac.
