Nice idea. I just struggle to understand how it is supposed to work.
When set up as in Studiologics images, the computer slips downhill onto the keys. When set up the other way around, the computer slowly moves away from you. I think if I place something there that has feet, it will be fine, but I will need to find a new home for my laptop.
It's not a computer plate. It's a slippery surface that requires whatever is on it to have feet, or be attached by some kind of velcro or something like that.
I'm giving 2 stars to the total, because it is a great idea, in theory.
