For the Nexus Q to work, you need to own an Android phone or tablet with Android 2.3 or higher installed. Introduced along with the Jelly Bean flavored Google Nexus 7 tablet and almost immediately available for pre-order, the former is going to be a tougher sell than the low-priced ASUS built tablet. Still, we're sure there will be those who find the Nexus Q to be a useful party accessory. And if we see some people staying away from their local movie theater in light of the tragedy in Aurora, the Nexus Q could be more popular than expected.
