It just looks like a perfect gaming handheld to me and shows again why x86 handhelds won't compare. It's affordable, small, doesn't get too hot or have loud fans, and has a superb battery. ~25 hours on low-end emulation is a dream.
I'd still wait until they're available and not pre-order, but it does look tempting..
Emulators, mostly. There's some PC ports for android that play well like dead cells and stardew valley, too. The people that made Skyline (the Switch emulator) are also making an app to run Windows games, but that's still going to release next year.
