My wife has the nice one, but she got me the sleeve by mistake. I have to say. I kinda prefer the sleeve. It has a place for the stylus whereas with the book folio you have to rely on the magnets. Granted the magnets are really good and a satisfying way to hold onto the stylus, but it is harder to trust when you are on the go.

I also like using the device by itself. If you want more protection it you are out and about a lot you can get a much cheaper plastic folio from Amazon. They aren't as durable as the one from remarkable but they probably do a better job protecting the device as they are rigid and the official one is not. We have those for the kids. They have dropped them. The case cracks but the device is fine.

As for the stylus. You can get them cheaper elsewhere but not sure I can recommend it. The magnets are weaker, the response not quite as precise and the eraser side isn't accurate.
