As long as the technology works for you Eric, and you're actually getting the results you want from it, then you don't need to fully understand the bare bones
I don't think age should be a barrier to technology either. If you've got the interest in it to begin with, then that's half the battle.
A few years ago, when Windows 95 was the current Operating System, I put myself through some college courses to learn
Computer Configuration & Maintenance and
Networking. I learned how to diagnose hardware faults and how to build a computer from the base upwards. I also learned how to network computers for home use and in an office environment.
At the end of the course I got my City & Guilds certificates and could have gone into a computer administration job if I'd been so inclined to follow that path.
However, the knowledge I had gained was really for my own benefit. I just wanted to have the confidence to deal with any computer problems myself, instead of paying extortionate charges for calling out computer engineers.
The knowledge has enabled me to do just that.
I too am inclined towards going for an Apple MacBook Pro when my current laptop decides not to play fairly with me and needs replacing. However, the cost of Apple Macs are considerably more than Windows PCs, so unless they come down drastically in price I may have to resort to staying with Windows. (Unless I win the Lottery of course
)
Regarding your iPhone panorama photo here, I can see it all on screen at once without having to scroll. I do have a widescreen laptop so that's the reason there. I wanted a big screen area for all the graphics work I do, so that was the reasoning behind it.
