Airman 1st Class Dustin Turner, right, 319th Communications Squadron, trains Col. Timothy Bush, 319th Air Base Wing commander, how to operate his new Lenovo Think Pad X220 business notebook at the wing headquarters building Feb. 27, 2012, on Grand Forks Air Force Base, N.D. The new computer tablet is one of 100 new state-of-art notebooks purchased for the wing's most recent initiative to modernize the technology on base. The 12-inch notebooks weigh less than four pounds and their wireless feature will allow personnel to perform nearly every single task they routinely do using their grounded desktop computers, such as reading and sending e-mails, doing online training and digitally signing documents.
