Ok, Glass.

Let's see who wants to buy a wearable computer.

Google opened sales of Glass to the general public this week. In a Google+ post announcing that the device would be available for anyone willing to pay $1,500, the company said, "We're still in the Explorer Program while we continue to improve our hardware and software, but starting today anyone in the US can purchase Glass Explorer Edition as long as we have it on hand: www.google.com/glass."

So take your pick of the colors -- tangerine, sky, shale or cotton since charcoal is already out of stock -- and hand over the money if you want to join the ranks of the gadget-wearers.

But what would you use it for?

A newly available set of apps, including Foursquare, TripIt and OpenTable, seem to emphasize Glass' potential usefulness as a travel device. Google Glass already offered Field Trip (for learning about nearby landmarks) and Word Lens (for translation).

"Whether you're trying to find your gate at the airport, the best coffee shop in Austin or a reservation for 2 in New York City, Glass has you covered," the company said.

Just don't forget your charger at home or the hotel. Seems to me that's always the trickiest part of traveling with gadgets.
