I read the Head First books on my smart phone quite a bit. In some of the Head First books the code snippets are graphics and then there are additional graphics illustrating the concepts. Often I cannot stretch the graphics on the phone to read them and I have to wait until I get home and can read on a standard screen to understand the section. Do you know if this book is more smart phone and kindle friendly than some of the previous Head First books ?
Probably not, I don't believe that O'Reilly has changed how they generate the eBook files. Unfortunately, because of the way Head First books are laid out, in order to maintain things like the position of the graphics, annotations, and such, it's very difficult to generate the pages in a mobile-friendly way.
Have you tried viewing the PDF on your phone? I don't know if that would be any better. The PDF works really well on my iPad, I can zoom in etc. I think I'd have a hard time reading it on my phone though! My eyes just aren't that good.
I understand that the illustrations have to stay as graphics but I was hoping that the code snippets could be set as text not graphics, perhaps they are in some of the formats other than Kindle.
No, I haven't tried the PDF on my phone but I will experiment with that and with the epub version.
I love that O'Reilly lets me download ebooks in multiple formats. I recently starting using the O'Reilly option -- "Upgrade to the electronic version of any print book you've registered at oreilly.com, for just $4.99." I end up reading more because I can pump up the text on the ebooks when my eyes are tired. It is great to be able to cut and paste the code into programs from the ebook. Plus -- the ebooks are not so heavy to carry around. I seem to read mostly in the epub format now.
