Note that the Kindle version and physical copy story are not exactly the same.
Can you elaborate? What differences do you find? Just curious as to which I will I will purchase
word is that the book versions have now been edited/updated to match that of the kindle. I cannot confirm that. I can only confirm that the book version I have - straight off the original release - has differences that appear to be directly linked to what might have been a cut/paste style method used by the author when taking text directly from the original Alice in Wonderland story.
depending on how you approach your problem solving, the choice is important: Notes/writing in book/underlining/ etc. you will want the physical copy. If you would like to look at the text electronically to a) be able to simply copy items you want to research/Google and search for keywords or key words; b) to have other references (such as Alice in Wonderland) pulled up alongside for comparison; and/or c) like a make electronic notes, files, highlights, then going the Kindle Version is the way.
