Cloud gaming is solution looking for a problem. It's not customer demand driven. Nobody want's cloud gaming (at least not yet). They haven't shown anything compelling why this would be a game changer for end users. The games are not more fun or unique than on any other platforms. Any of the cloud arguments also hold for consoles or PCs on internet connected games. I think the site may be a bit optimistic.
Every time someone posts "Nobody wants cloud gaming" half a dozen people come in and say "Actually, I want cloud gaming" Don't mistake the fact that you don't want cloud gaming for nobody wanting cloud gaming
So clearly there are plenty of people who want this and are even willing to risk it being total crap at $130 each.
