I need the bare minimum grip cover. I went to the Apple store to try out the incase silicone covers, and was amazed at how "bulky" they felt. They added significant heft to the iPad, the edges didn't feel like the adhered very well to the iPad, and perhaps worst of all, the silicone was slippery, not grippy. My new fantasy cover? A rubber-band like strap that form-fits around the edge of the iPad, adding a bit more grip and providing a bit of edge protection. In the meantime, tell me which rubber/silicone covers are the best, minimalist.
