Thanks for the article. The part I found interesting is that vibrations in certain areas can make the sense of touch go wonky. Makes one wonder sometimes, but then again I could've told them that. My numbness always gets worse when it feels like I'm buzzing and vibrating.

Touch screens have definitely made things interesting. Hubby asked me if I wanted to get an Iphone, but I can barely get it to work right. I often press too softly for it to register anything. So I told him "no thanks" and am sticking with my buttoned cell.
