Except for the fact that you don't. I looked it up because if it were true id buy one. Rather than something thats colourfull, soft and similar to the apple smart cover. Its thick, solid, gray, there's nothing that says either way but I doubt i can flip it round the back, let alone flip it round the back and it deactivate and turn on the on screen keyboard. In fact there no real explanation on what affects which keyboad gets used. Do I have to manually go into the Bluetooth settings? And lastly to make it stand up the iPad you actually have to stand the iPad in it.
This is in no way similar to the surface keyboard.
Not to mention there is far more to the surface than the keyboard.
Surface RT is very similar to the iPad. It's the Surface "Pro" that's sufficiently differentiated.
The iPad keyboard question is covered by standard behavior, not specific to that brand of product. If you have a Bluetooth keyboard paired and turned on, the virtual keyboard does not activate, it just reads the BT keyboard.
If that model doesn't suit you, there are plenty of competitors.
I think the stand property of the Logitech has a distinct advantage, you can set the iPad in either portrait or landscape. Surface doesn't seem to have that ability, it's landscape only that I've seen.
