Don't forget the youtube video:

Also Sonic2 could be played with the megadrive controller, you can connect multiple types at the same time, but if it has all the buttons I guess it would work either way.
I didn't know I wanted one until I had seen it in action.
Exagear can be used to run windows applications, it's like a combination of a tweaked QEMU and Wine (x86 emulator + windows emulator*). But it does not do 3D, so out of luck for running all your pc games.
The company building it runs Skype for x86 on arm-linux as a demo, so I guess people running applications from their office portfolio might get really lucky with this tooling.
But I would guess a lot of non-game applications are suitable to run on the pyra, who knows maybe you can run visual studio on it or microsoft office applications (which is a big deal for some people that aren't happy using LibreOffice).
(*for sake of explaining what it is without going into details why it isn't an emulator)
Also Ptitseb is there (more nice people are there of course!), due to him I could play half-life on my pandora in the waiting line. Thanks for that
(Also played some jazzjack rabbit 2 done by Notaz, also: thanks you Notaz)
