Do you guys actually prefer your mechs to be non slip? I realize that the rubber feet tend to be part of package that is reviewed when we look at new boards, but generally I don't find a problem with the board slipping across the desk and in fact prefer for the keyboard to be easily moved slightly without needing to lift it up. Some boards like the Cherry 3.0 actually include extra rubber feet for grip.
I spend most of keyboard time in the office split across typing emails and working on spreadsheets, in general sitting in front of two widescreens positioned horizontally and at an angle pointed towards myself. At the same time, there would typically be some kind of (paper) notebook as well as a smartphone or two on my desk which I use my Filco Convertible with. This is paired with a large-ish wireless mouse. This means that I am usually angling the board towards which ever screen I am looking at, as well as an occasional shift back / forwards to make space for paper documents / other people invading my space to work on something together on my workstation.
As a quick and dirty fix, I usually just tape some paper underneath the rubber feet that makes it easier to slide around (no points for presentation I know), is there a common workaround that folks here prefer?
