I see there are different versions of this book, which one should I buy?
Hey @ralphc-nyc I actually only saw two versions of the book although it does come in multiple formats like paperback and Kindle. Regardless, I would get this version:
The revisited version has all the same stuff as the first one, with a new chapter on mobile usabilityand more up to date examples.
If you’re just starting out and want something super cheap (second hand) to give you insight then the first one is great and still a fantastic book. If you are a bit more experienced, or are happy to spend a bit more on the newer one then go for that!
