It has same protection as hardcover notepad, but it is very flexible to swap in new pages. Thanks Thomas, great idea! I cut an unused plastic pocket folder into two slightly-oversized covers for the hPDA. You can easily read through the covers, but they provide a lot of protection for virtually no extra weight or bulk. These rings open easily for sorting or swapping cards. Use two rings for a “flip top” approach or just one for the max in random access.
