The AVP failed on price, yes, but also the limitations of the software (and lack of content, which I think go hand-in-hand).

The AVP was just an iPad that you strapped to your face. Yes, it had apps, but they could only do more-or-less the same things an iPad app could (in 3D, sure).

That's why I returned mine, it was way too limiting of a platform for the cost. This, while cheaper, is even more limited (no apps).
