I really like the ChillTab. I also have the funky Apple folding cover thing, which is nice for carrying round but a little flimsy for serious use. The things I like about the ChillTab are: (i) it’s sturdy and stable, I use it in the kitchen as it provides a safer place to put the ipad down (much safer than lying the thing flat with the kids around), (ii) it provides a good viewing angle for either using an external keyboard or showing videos to the kids. For me the stability (and the fact it keeps the tablet away from my kids spilling juice or milk) is the best feature.
