The thing is, not many people want to attach anything like that to their phones or tablets. Secondly its a hassle using a wireless or blue tooth device outside of something connected to a TV or a Monitor. Can you imagine how silly it would look being on a train or anywhere else trying to juggle all those devices and controls? Also attaching a controller to a Phone looks silly as well. You sacrifice some screen size and other functionality of a phone, but you get a dedicated device... one that is dedicated to running games smoothly and efficiently. No more sitting around adjusting settings to get the smooth and best playable game settings and hoping you don't reach a cut scene or portion of the game where the emulator goes to absolute hell. Also most of the emulators on the GCW-Zero are already complete and are working near 100% of how the game was meant to be played or better! Many emulators struggle to emulate the SNES SFX chip efficiently... I still cant find an android emulator that will run Star Fox for SNES nearly as good as the GCW-Zero. The Zero is built for open source indie gaming and emulation and it has Wifi and HDMI out, you can really have a lot of fun with this device and know that its made for gaming. Secondly why do people like gaming on phones ( maybe tablets are better about this ) when the screens get super hot? Your draining your battery.. I mean I have an HTC One X and it emulates SNES very good, but at the end of the day I need my phone to be a phone. I have an extra pocket for a small affordable device such as the GCW-ZERO any day. And I love that it's smaller than a PSP.

Many people generalize that android can run all emulators and games perfectly. Theres still a large amount of games that can't be emulated properly. If that isn't a problem for you then by all means have fun with those android devices. But for those who want a classic experience with a device that is dedicated to play games and won't have other apps and programs in the background chocking the system or slowing emulation down and having glitches, they are better off with the gcw-zero. The device has buttons, HDMI out, and is specifically made for open source indie gaming and already damn near perfect classic emulation. Many android emulators still struggle to play games with SFX chips in SNES games. Still haven't seen starfox running as perfectly on an android device as it does on the GCW. You won't need to know much about options and emulation settings to get the games running smoothly either. Check out the youtube videos, and use your android for newer stuff.

Hardly, this is run on a version of linux and many of the emulators and apps can be carried over and developed in an environment which is specifically for emulation and open source gaming. Android and DONT even get me started on iOS have its issues with being their own entities and devices which perform specific task (organizer, phone, overall multimedia device) but these take away from emulation. In this environment you can have full speed on games and apps without having to cut corners so that other background task of the OS (android and ios in this situation) can perform as they normally would. This device is specific to gaming and most of all it has buttons! And as a plus has HDMI out! Unless you want to walk around with a bluetooth controller and your phone or tablet of choice, this app will run circles and will perform much more efficiently then an android and ios platform emulating games... Also its truly open source without restrictions and having to hack and modify a device to get your moneys worth.
