Living Mobile and My Follies in Computer Platform Knowledge

In the past 24hrs, I’ve been asked by two people questions that relate specifically to functionality and features of Windows 7 and Apple OSX laptops. The questions threw me for a loop in part because I was asked. But, the other part of the loop came because I’m nearing that point where my knowledge of whatever problems and opportunities lie in fixing issues related to getting the best use out of those "dekstop’ operating system platforms has pretty much gone dry. And I’m not the least caring that it is.
