I agree, some cushioning is vitally important.
As I prefer to be barefooted and my floor has no carpet or padding whatsoever my heels started to hurt at the end of the very first day. On the next day I felt that pain from the very beginning, so being productive was out of the question.
Contrary to the general consensus I got myself a really cheap gymnastics mat for less than 20EUR which is only 2cm thick, instead of an expensive special purpose mat.
Within 2 days the pain was gone and standing/working for more than 10hrs a day was not a problem anymore.
So get a mat or wear shoes if you plan on trying a standing desk configuration.
If you call that bold, ok.
I call it: easy to read and less strain on my eyes.
Especially because there is no need for ClearType (et al), which I can't stand, as it always looks blurry to me.
