The Yun is pretty cool.
In addition to the Arduino compatible ATMega-32U4, it has an Atheros AR9331 running linux.
From?
##############
The Atheros processor supports a Linux distribution based on OpenWrt named Linino OS. The board has built-in Ethernet and WiFi support, a USB-A port, micro-SD card slot, 20 digital input/output pins (7 of them can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, an ICSP header, and 3 reset buttons.
The Y¨²n distinguishes itself from other Arduino boards by its ability to communicate with the Linux distribution onboard, offering a powerful networked computer with the ease of an Arduino. In addition to Linux commands like the cURL, you can write your own shell and python scripts for robust interactions. The Y¨²n is similar to the Leonardo with the ATmega32u4, except that it has Linux on board. (has built-in USB communication, eliminating the need for a secondary processor).

If I needed python and WiFi and such, I'd probably look first at a Raspberry Pi.
But the Yun is an interesting alternative, and would support all the Arduino ATMega libraries.

Why would anyone be interested in swapping anything for a yun? It's essentially an Uno/Nano but at 10x the price. For less than half that price, the Teensy 4 has 2MB of flash vs 32KB, 1MB of SRAM? vs 2.5KB, and is clocked at 600MHz instead of 16MHz. I wanted to see what that really means for a book I'm working on, so I wrote a simple loop that does nothing but increment a counter for a 1 second time slice. The results;

???? Yun??????? ????????Teensy 4.0
??? 7,303???????????? 199,979,425

It's not a fair test because the counter needed to be a 32-bit long, but still...

To me, paying 10x the Nano price (and over 2x the Teensy 4.0 price) isn't worth it for a few more analog pins and 512 bytes of SRAM.
