Well, at least the 3DS has proper Snes audio emulation; Snes9x 1.43 sounds like shit on PSP XD It can't even get the sound effects right lol.
nVidia Shield K1 is good, I recommend avoiding those Chinese portable consoles, they're riddled with firmware issues.
Indeed, the GPD XD is great, but its very much bugged hardware wise. Place a Samsung S6 fast charger in it and it fries the circuitry (No communication protocol for acknowledging correct current). Also charging it while turning it off or on can damage the screen circuitry

My Pandora runs on 1.1GHz and the emulation support is hugh. It emulates the dreamcast, n64, DOS, ... oh and it has Cortex A8 +
PowerVR SGX GPU. The GPD is powerful I agree, but how about a keyboard for eg. Amiga or how about multiplayer support? Maybe the GPD Win or Open Pyra would be the best for me.
Yes, the keyboard for me would be a deal breaker indeed in particular to also use it as a compact Amiga or C64 rather than just games.
