I don’t know that I’ve used enough handheld Linux devices to say. The only major one was I had Debian on my Surface Go 1. Power management never worked quite right - after a few suspends, I’d get these weird graphics glitches and have to reboot.
Also, I kind of hated the keyboard- it wasn’t very sturdy and often flexed, causing accidental trackpad clicks.
I still have the device, but when I need a portable Linux machine, I just go to my Thinkpad these days, which other than installing the backports kernel for Wi-Fi support and then adjusting the modprobe.d entry because it was Realtek pretty much just goes brrrr - even my desktop gave more of fuss, as I used to be in a room without ethernet and needed a card that worked with Windows, Linux, and Hackintosh (from before I got rid of my Windows install and my Hackintosh SSD conked out, leading me to switch to virtualization).
