Gamers seem to have backed this based on an idea that it's a $100 full fledged console. It is not. It is, at best, a tablet that hooks up to your tv and has a controller. At least as far as the hardware is concerned.
On top of that, their release timelines aren't even remotely realistic. March? They don't even have their online store prototyped yet. They have some UI mockups and that's it. Launching in March? Yeah right.
And then there's the issue with allowing the console to be fully open, using a hardware platform that is already having so many issues with piracy that developers are slowly being forced to release their games for free and supported with ads to make any money.
I have no doubt that if this system ever materializes, it will make an impact, but it's a long stretch to think you'll be taking delivery of this system in March and playing Final Fantasy 3 on it.
