That's one of the arguments online. It is for everyone, yet it isn't. For people who are part of the Sony gaming culture, it is essential for streaming PS4 to other TV's in the home, or playing your Vita library on the big screen.
But, as the article above talked about, Sony also has positioned it to go up against the burgeoning Microconsole market. But the market is in the process of trying to figure itself out. If you want an entire setup, the discussion online is wondering if it is really worth it.
As far as pricing:
VitaTV w/ Controller + 8 Gig card: $150
Ouya w/ Controller + 8 Gig internal: $99
Wii System w/ games: $129 (drop to $99 or introduce Wii Mini worldwide?)
XBox 360 w/ Controller, DVD + 4 Gig internal: $199 (drop to $149 this holiday?)
Sony PS3 w/ Controller, Blu-ray + 12 Gig internal: $199
AppleTV: $99 + price of controller (no App Store & Gaming yet uncertain)
So as a Micro-console, is it a bit overpriced?
I would love to get one, as I love my GB Player (though it needs a GameCube) - kinda cool using carts on a Microconsole - so Retro...
