Cameron: Fair point, but I think the fact that this is a portable device distinguishes it from the OUYA (which can't compete with other home consoles).
Maighstir: Then again, it seems to fall in the same category as the GP2X Wiz, Caanoo, Dingoo, and Pandora, and I can't recall any of them being hugely popular.
The Pandora didn't fail, after Michael Mrozek took over the whole project, everything went fine and all units will be sold soon since some of the parts are out of production but there is still demand and the community is very active and the software very polished (PSX in higher resolution than original fluid on 6 year old hardware, woohoo).
I had a "GP2X Caanoo" and it was quite good but battery life had only about 4h in it and (unlike Pandora) the battery can not be changed easily. The GCW0 is it's spiritual successor but since there are massive production problems, the community for it is really small and it still lacks some important software.
I'd rather get an OpenPandora or wait till its successor (Dragonbox Pyra) is ready but this may take some time, although it's making very fast progress, since Michael knows what he is doing unlike the former Pandora producer Craig Rothwell who is known as kind of a "Sir Scamalot" by now by many.
Since I have my OpenPandora and made an upgrade to the current version, I sold my Caanoo and am very happy with this lovely swiss army knife of hardware and awesome battery life. Since I love DosBox on the go, the physical keyboard is quite important, like in Amiga emulation.
10h with screen, way more without it as an audio player and since the sound chip is a very good and expensive one, the sound is better than any mobile music player on the market and it actually makes sense to load flacs into it, which is no problem since it can run with two 128gb fullSD-cards at once.
