I have owned my IPad1 for one year now. I have seen people with the wireless Apple keyboard and they have all expressed they are not happy with it. They don't like the fact you can't tell if it is on. They also say they don't like that it is not attached to the IPad, like in a case.
About one month ago I purchased the Kensington, all is one keyboard and I LOVE it. I am almost redy to give up my laptop. I love that it has a case that it is attached. I can completely cover the keys if I need to, by laying the IPad on top of the keys. I can also stand it up so it is more laptop like. My keyboard has a switch up flip up and you can tell it is on. It automatically connects to the Bluetooth. It has made such a difference when I type a lot. Save money on the case and buy this one and you get both.
