Why is it surprising? This is essentially a pre-built PC in a small form factor and most PC peripherals are USB-A.
I haven’t seen a new product with USB-A in years. It’s long past time to move on.
My 4 year old (maybe 5?) work laptop has 3 usb C ports. My macbook is all usb c, and my home media/gaming PC has a mix and match.
All my cables I would connect to my home PC/macbook are USB C. IE bluetooth adaptor, sd card adaptor, external ssd, mouse/keyboard, a soundbar etc.
I have several chinesium clones of dewalt batteries/tools, IE lights, compressors etc. They all have USB c output.
"most pc perihpials are USB-A" is not exactly correct for some time now. (not that I'm a fan.)
No?
The only PC peripheral I have with USB-A is a mouse dongle when I'm lazy and don't connect bluetooth - and that one I connect to the monitor.
All others are usb-c.
