Pricing is definitely GPD’s issue, but yes hardware issues as well. I have a Win Max 2, and it was neat at the time, but it costs way more than a Steamdeck and really isn’t as powerful. When you play a game on it it runs so hot and the fans are like a jet engine. I pretty much use it as tiny laptop these days and use the Steamdeck for any real handheld gaming.
I adore my GPD Win Mini, they’re the only ones putting out good pocketable clamshell devices and I adore them for it
I use the GPD pocket and its magical when flying to roll up with a laptop on a plane with a 9-inch screen. My model even has an i7 in it so it can handle some games. Only major complaints is that I had some issues getting the screen to play nice with wayland (Ive since fixed it, it was just effort) and its keyboard is an ergonimic train wreck.
Yeah the native portrait screens they use cause all kinds of weirdness on Windows for games, but I’ve solved that by running Bazzite. I only use mine for gaming most of the time, my Win Mini’s 7840U is a fantastic chip both for hooking up to a lapdock for software dev and for handheld gaming.
I’ve only flown a few times but it’s been a great way to pass the time
