Apparently, I haven't kept up to date with the HMTL5 advances, especially around the mobile world and, therefore, the future of the technology is all new to me. This book makes the future look pretty good and interesting.
At around 150 pages, it doesn't take long to read it, while the author wants you to understand the HTML5 concepts
in different environments, i.e. mobile, desktop, tablets etc. It provides a general approach of what is going on in each environment, giving a few small examples in order to start you up on how each one works now.
