The Rio Hotel in Las Vegas has added a new Surface computer with Microsoft applications to its lounges. The Flirt allows barflies to chat with each other via text messages and web cams. Mixologist lets patrons design their own drinks and send them to other tables. Shaped like a table, it features a 30-inch display that uses infrared cams and a projector that creates a 360º touchscreen. Harrah’s also has plans to test the technology this year and add to it with a “Virtual Vegas” guest guide and computer games. At a $10,000 price tag, that means a whole lot of creative mixology and gaming for any bar thinking of investing.
