I use hardwired laptops in my examining rooms and they stay there. They are 17 inch fujitsu N6460. Plenty of screen and to big and too heavy for anyone to try to steel it. They worked very well in last 4 years.
We use hardwired 15.4" laptops in each exam room. They are secured with a lock cable bought on ebay for $1. Plugs into a security port the laptops came with, and then we drilled a hole in the wooden desk it sits on. I think it's mostly for show, but so far no problems.
So we have hardwired laptops in each room plus desktops in offices. We've thought about switching to something providers can carry instead of having so many machines, but this has worked well 4 years.
