From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

You lose the I/O and power efficiency is no comparison. You can get better power efficiency and sometimes some I/O with an old router and OpenWRT, but you'll be in the class of a Beagle Bone and a much harder learning curve. I've never managed to get a sensor or peripheral working on some old laptop's SPI or I2C buses like how easy it is on a Rπ.
New low end chromebooks are much better for this anyway, an intel N4000 will consume just 8 watts at its peak and it's even supported by Windows 11, and they are usable if you put Linux on them
You can get an esp32 or whatever and have io
