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).
Funny, but the truth is most warp cores from 2375 have secretly been powered by the suffering of transporter clones of Miles O'Brien made without his knowledge while he taught at the academy. Eventually, when people found out what actually powered ships sometime before the 31st century, O'Brien warp propulsion was retired and dilithium was brought back into use.
