So last week, when Chapters / Indigo was featuring this book, I figured I had to buy it.
I must make the disclaimer that I don't even own a Smartphone, so QR codes are lost on me any way, but this book is laugh out loud funny in the examples that the author has found to illustrate his premise. A technology should not be used, just because you can.
If you get a chance, read this book. You can also watch a presentation by the author, on YouTube.
And, in case you are wondering, I bought the book, and the review is my own opinion.
