It looks like my wife's MacBook Air (11-inch, Mid 2013) and my iMac (27-inch, Late 2013) will be able to run macOS Catalina. Damn! The longevity of a Mac is incredible!
I got my first computer in 1980 when I was 14 years old. I had begged my father for a computer for my birthday and he bought me a brand new Commodore VIC-20. It was one of the most popular computers of its time. I loved that thing and spent many hours learning BASIC and programming my own games. My grades dropped because I was so focused on using that computer. My father had to take the computer away until my grades improved.
When the first child got a computer when they were just a few years old. It was an old Windows PC running Windows 98. I installed a few simple games allowing them to make things happen. When they were older I bought an iMac for the entire family to use.
But their very first personal computer was my hand-me-down iPad 2 which I presented on their 11th birthday, followed by an iPhone when they started high school.
My nephews are much younger than my kids and started using these devices much sooner; elementary school. I think that was a mistake. They can’t function without them. Going out to dinner I see my sister-in-law struggle to keep them focused on the meal or even just casual conversation.
These are the things I treasure. My iPad allows me to create the newspaper of my choosing. It's also a mobile photography studio. I can use apps like Adobe Lightroom Mobile and Photogene to edit my photos while sitting in a cafe after a long photo walk. My iPhone is my mobile office. As a consultant, apps like Freshbooks and Tempo allow me to conduct business from anywhere.
My Moleskine note book keeps me sane. While writing apps like Byword are useful I find putting mechanical pencil to the Moleskine helps me clarify my thoughts.
The iMac is where I set to do the bulk of my photo editing and blogging. Of course, I need music. Streaming trance music over my Harmon Kardon bluetooth headphones calms the jumble in my mind and helps me focus on the task at hand.
Treasures. All of them.
