I have never used the Apple Smart Keyboard before and tried it today at the Apple store with the 10.5 iPad Pro. 1. Do you get used to the keys spacing over time? It was unusual/uncomfortable to type on the keyboard compared to other keyboards that I have used. 2. It is very expensive and I am not sure if it adds any value to something like a $40 JtechBluetoothh keybaord that I use. Your thoughts? 3. The back of the iPad is exposed. Thos of you who use this keyboard, how do you protect the back of the iPad?
