Print & PDF. While I read a lot of books on my iPad I have yet to read a technical computer book on the iPad... usually because they are too big and I prefer to read smaller books on a tablet. So I guess my real answer is it depends on how many pages in the book. If it's over a certain page number I'll be reading the print version.
It surprises me that number of pages is an issue. Now page size as an issue I can understand - if there are full page diagrams, or even worse diagrams that spread over two pages, and the original page size was A4 or American Letter or Foolscap, that won't be viable on a small screen device.
