Anyone looking at my desk today could be forgiven for thinking they had stepped into a time machine. An OLED TV and Nintendo Switch on the other side of the room would reassure them this was indeed 2018, but the desk is firmly planted in 2011. There's a MacBook Pro (Early 2011), a Mac Pro (Mid 2010), and an iPhone 4 (released February 2011). Look closer and you'll also see that all three devices are still running operating systems from 2011: Mac OS X Snow Leopard and iOS 5.
Perhaps I'm a Luddite, unable or afraid to upgrade to the current OS versions? Or maybe I'm too poor or cheap to upgrade my hardware, the last time I could afford to do so was during Obama's first term? I assure you that neither of these are the case. In my day job I run a network of Macs running the latest OS. Said job also provides a paycheck that I could use to buy new computers. In fact, those Macs were acquired this calendar year, but they are older models I got through Craigslist. I can and do run newer Mac OS versions inside VMWare or by booting from another partition when necessary. On the iOS side, I have an iPad running a recent iOS. So I'm perfectly familiar with the various Apple OS updates, but I choose to use the 2011 versions instead.
