32GB of RAM so you can always set textures to high quality. fast 1 TB of storage. 

The controls are excellent - great sticks and you have choices of soft membrane buttons or clickier dome switch buttons. the 6 button arrangement for street fighter (or sega saturn) games is really cool, too

great I/O has 2x thunderbolt 4 ports.

has an Oculink port for faster eGPU setups!

headphone jack

SD card slot

It's pretty rare to find a device with the OLED screen, the oculink port, and with a reasonably priced APU. 

The unit is currently running windows 11, but it can also run linux. I used to run bazzite on it and that worked very well, too.
