Technomadia is the REAL DEAL and their The Mobile Internet Handbook is too!
The authors know what they are talking about. Their technical knowledge is superb and as up to date as it can possible be ... and when things get out of date, they quickly update what they have written to be sure everything they have said is as current as it can possibly be.
They do a good job of explaining in non-technical terms what a user of mobile internet connectivity needs to know. And if you are a technical whiz, you will appreciate the work they have put into their book and the wealth of detail that they provide.
Thank you, Cherie and Chris, for providing one of the best resource handbooks I have ever used~!
