Actually I never heard of this device before and it seems a little... useless for me.

I'm still not convinced of android as a gaming system and so the only thing left would be emulation. (And that's what the manufacturer seams to be pointing at).

However I feel like I could get the same out of my phone by using an Bluetooth controller for a much lower price (since I already have a phone). Plus getting the benefits of probably longer update support.

Maybe for people wanting to use a smaller or low spec phone and have a separate device (only for emulation) on the go, this makes more sense.
