Compatible with an iPad. From CNET 2010 "The iPad keyboard dock provides a sturdy, full-size keyboard to accommodate typing-intensive apps, such as e-mail and word processing. Offers a functional and elegant solution for anyone who finds the touch-screen keyboard too limiting." Measurements: Keyboard measures 11 inches wide and 4.5 inches deep, and stands just 0.65 inch tall toward the back, sloping down to a mere 0.25 inch at the space bar. The white plastic dock fused to the back of the keyboard gives the accessory a total depth of 7.25 inches.
