I can't believe you guys. You don't want the Zero to be a commercial success because someone you don't like might also get one? Pretty weak... pretty fucking weak, actually.
It should be said though that the Zero is unlikely to attract the "12-year-old, Bruno Mars hipster jock thug" crowd, given it's specs compared to something like a Vita or high end smart phone. Let's keep it real - this is a niche device for retro junkies, and that's primarily - if not solely - who will buy it. Whoever wanders over to this forum is vastly more likely to be just like you guys than the typical CoD buckwheats.
Is it worth it? Absolutely! The more units GCW ships the better! More incentive for them to make a bigger, better, follow up unit, more potential devs, a bigger audience for any devs that want to market their games on the system... and you want to give up all that because you're butthurt about the possibility others will "encroach" on your turf? Yeah... pretty weak.
