I haven't purchased this yet. While reading the detail description I was impressed because it lists the number of available pages, it's tab alphabetized, and has some extra pages in the back to write important numbers such as serial numbers, the type of program, ect. (needed to find especially during PC problems). Many other organizers only have 25 pages, and some companies don't even list the page or assets the organizers have. You've done a wonderful job with the details which helps a lot when deciding on which one to purchase.
