Rocki as good as it seems?

As with most CES's, there's a lot of cool stuff; but most of it is just too gimmicky (useless) or expensive for me. The same is true for this year, with the exception of Rocki. (Yes, I know it is a Kickstarter project and not announced on CES, but CES is what brought it to my attention.)

Lately, I've been trying to find a simple solution of getting my music library to my simple stereo set. Currently, I'm streaming music from my iPhone to a jailbroken iPod that functions as AirPlay receiver.

I was under the impression that Rocki used a different protocol and wouldn't work with or like AirPlay - only via a dedicated app. But it turns out that they went through Apple's certification process and that it now support AirPlay. This would mean I'd be to stream audio from any app to Rocki.

If this is actually true and the Rocki works as well or better than AirPlay, then it's a no-brainer for me: I'm going to sell my iPod and buy this thing.

However, I'm slightly confused since I've done a lot of research in the past and know of no other cheap, dedicated AirPlay receiving device. Why, all of a sudden, does a Kickstarter project manage to do this when years have gone by without any other company managing to do it?

Is it too good to be true, should I wait for the reviews or should I just buy the thing?
