So, a couple months ago, I had to replace my glasses (The prior pair's arm had broken in a manner that could not be repaired.). Having reached a certain age, I needed progressive lenses (I had them in the last pair, which means I reached that certain age a while back.).
Now, as this (intermittent) blog indicates, I went all in on iOS a long time ago. That said, I have a Mac Mini at home to serve as a base of operations and a Mid-2011 iMac on my desk here at work. One of the things that has troubled me about this pair of glasses is that the progression is off. In my last pair of glasses, I would look at the iMac's screen and all would be clear. Now, it is fuzzy and I have to tip my head back.
Just moments ago, I finally figured out why. The progression is not set for people who work on a desktop. It is set up for people who work on a laptop or a mobile device, like an iPad or an iPhone.
A number of the podcasts I listen to are populated with people I respect and listen to bemoaning about the death of the Mac in general and desktops in particular. Apparently, it is not just computer companies that have begun to adjust to a post-PC-of-their-memory/imagination world.
There is more potential angst to this than that supplied by aging tech pundits. This kind of change should be noted by the academy, which is a much more conservative and stodgy group than usually imagined. Perhaps we should begin to consider changing some of our ways if and when our glasses are letting us know that the world has moved on.
