Quick Review
I had been developing software for about 10 years... and am just finishing up a grad degree in CS after going back to school... If found this book to be a LOT better than all the hand outs that my prof put together... It's a great book to give you an overview of all the problems in mobile computing... and a lot of the answers... (not all :-)). As the other reviewer says, it's priced a bit high at $85.00, but I found it to be well worth the price I paid... hopefully the prof takes my recommendation and uses it as the text book for future classes...
My View on Mobile Application Principles
Please excuse English. This is a very good book for learning mobile applications in US and Europe. Also, a lot of good new things on UML and XML. But, I would have liked to see more on the Japanese Mobile development. I think this is good as a text book in class room or reference. I would like to have more introductions to UML than 1 chapter. The UML is more advanced in this book. Also lot of good location and voice informations.
