I've spent some more time with the Libretto, and am warming up to it. The cover has stretched out a bit and now closing it is not an issue. When folded back, I've learned to hold the cover slightly to the left (looking down at the case), so I don't accidentally trigger the sleep feature. It seems to be working out well. I hope Apple doesn't come out with some"must have" update for the IPad which will render my whole set-up obsolete (OK, I know they will eventually do this, but hope it takes them awhile).
It's highly likely next iPad will have retina display, and I would call that must have. Will make reading magazines on Zinio much better.
