I was going to buy "The Art of Electronics" from Amazon when this book, "Learning the Art of Electronics" came up in the search. Same authors, the cover looks the same. They are taking pre-orders as the book is not yet released. Does anyone know if this is legitimate or is it a ripoff copy of the original? It appears to be more lab oriented than the original. I am questioning the legitimacy as there are several grammatical errors evident when reading through the preview.
