Setting aside security. I have owned laptops from every major brand. IBM ThinkPads, Toshibas, Lenevos, Dells, Macs and ASUS. So far, other than ASUS, I've run into more hardware issues with these laptops with fewer repair options available. They've also had bad battery lives compared to the Macs at the time.
I've bought laptops and flashed Linux on them. I've used Ubuntu since Hardy Heron. But none of the laptops worked as seamlessly and as well as my Macs. The touchpad wouldn't work. The WiFi would fail. Sometimes updates broke the machine if they worked at all. Printers weren't plug and play. A few times the system crashed because of a configuration error that was unintentional. All in all, it was a poor experience.
The difference in the experience is summed up by what happens when you open the box. A new Linux laptop would require an install, then hunting down the files, copying it over, doing updates, changing settings, changing the configuration etc etc. A new Mac is simple. I bring it home. Turn it on. It goes on my WiFi, finds my Time Machine and does the rest. I have perfect continuity from my old machine to the new. I have settings and programs here from 3 machines ago.
I like to use my computer to work rather than working on the computer.
Moreover, from a security perspective, I trust a company like Toshiba less. Mostly because the Toshiba comes with a ton of bloatware installed; https://www.google.com/search?newwindow=1&hl=en&ei=hsR8XZmLF... and you never know what they might install. As of writing, my Mac just doesn't.
