My Steam Deck is my only gaming PC and is enough for my needs. I dual boot Windows along with SteamOS for when I need to do something that Linux makes too confusing. The Deck allows me to be outside of my office while gaming. I had a switch, but am pretty much done with it since I discovered Yuzu recently. For entertainment and light work, I use an iPad Pro 12.9. I thinks it’s a great combo for everything I need and want to do.
The Nintendo Switch Pro controller is my favorite. Before that, it was the Wii U Pro controller. DualShock/DualSense and Xbox controllers are always in the mix, but I always go back to the Switch Pro Controller. I do also like the Steam Deck’s controller (thought not a traditional standalone), while never liking the Steam Controller - as weird as that is!
