AirTab alternatives

A portable monitor which attaches to any PC or Mac through usb. Easy to use and readily accessible to the average consumer. As one of the first few people to test the product since alpha, I can say it is truly innovative. As a current law student, many times, I’ve had to synthesize an article or read cases to determine precedent. With Duo, I can have both the article and my Microsoft application open at any given time. I no longer have to view each separately. This is especially more convenient when on the go. The main purpose of the product, a portable monitor, saves one time and prevents frustration. All I can say is try it before you knock it because you’ll love it if you do.
