It’s $500CAD more for less RAM, a much worse processor, single monitor, lower top speed due to reduced thermal headroom, less & worse ports, no Ethernet jack, worse/no headless support and a battery that will swell up in a year because I leave it plugged in all the time.
If you have a desk and like to sit at it, this is a much better choice. For me a laptop no longer fits into my life. I do everything on my phone, and for what needs a computer I want a big screen, keyboard and chair.
To each their own. I think this is the best value product Apple has released in over a decade. At $669CAD for Education it’s an insanely good buy.
Thunderbolt is for permanently attached expansion (10gb Ethernet, eGPUs, multi drive enclosures, port expansion/docking etc) and USB is for quick connections (USB keys, SD cards, etc).
I seriously doubt anyone will ever use these ports for Thunderbolt devices, because there are very few thunderbolt devices that people use regularly, and if they know what Thunderbolt even is they know to look.
