Well Charley,
Maybe the term 'filthy' was badly chosen.
Personally I take great care of my Genos, dusting it every day, washing my hands before every session, every day. No chips, crackers, nuts, hamburgers, tacos or drinks in the vicinity!
But some people have greasier skin texture then others and they leave fingerprints more easily.
To avoid having to clean the touch screen every day I make use of this
non sticky transparency sheet and I just wanted to share it with other people having the same issue.
In summer when it is warm and humid, my finger tips tend to sweat a lot, so much even that I have to wash them every 15 minutes because they tend to stick to the keys too much. They won't glide over the keys. Using a small fan directed to my hands is another solution.
Just my 2 cents
