I've read all the threads I can find on the Ridge and watched several videos and nothing seems to adequately address lap usage. I primarily use my iPad in my lap on the couch and I'm wondering if the Ridge holds it's position(s) well in that situation. I've seen the Speck Fitfolio (next best contender) in person and found it to be totally inadequate. The little ridge on the Fitfolio is too small to be stable and the detents it fits in aren't deep enough to give it a lot of grab so it's constantly slipping. I really like the look of the Ridge, the fact that the bezel isn't covered, and the lightweight, slim design, but would really appreciate someone chiming in on how well it works on something other than a solid, flat tabletop.
