Hello, I am an EMS provider and we are issued Surface Pro 4's for creating our documentation. These are neat little devices and I could see the usage of them. However, we use them in the back of the ambulance on our lap, without the hard connection of the keyboard to the screen of a laptop I've dropped mine many times. It's useless to me unless I have a desk to set it on. Are there any cases or other keyboards I could use that would lock together the keyboard and screen so that I could use this more like a laptop, on my lap while driving down the road? Thanks for the help!
