It does have Google Play access. It's an interesting product and I'd quite like to have one but I can't imagine I'd ever want one anything like enough to pay for one. It's probably more of a concept product to promote the Tegra SoC and its possibilities because I think that market is Nvidia's highest priority.
If they stuffed batteries in the handles, they could get excellent battery life. I suspect the additional weight and cost would make this prohibitive. Shame they got the D-pad and left stick the wrong way around.
