The most convenient handheld gaming PC I've ever used is getting upgraded with an OLED screen, Ryzen HX 370, and a repositioned mouse nub (that's the best bit)
I've tested heaps of handheld gaming PCs, from the Steam Deck to the ROG Ally X, and the one that I keep on me at all times is the little-known Ayaneo Flip DS. This little clamshell device has a party trick: two screens. But that's not all it's good for. It's hella convenient, easy to navigate, portable as heck, and now it's in line for a big ol' upgrade.
The new Ayaneo Flip 1S DS (catchy) comes with a brand new, powerful processor. The AMD Ryzen 9 HX 370 is a powerful chip from the Strix Point generation.
