Thrilled with my new purchase and I just want to share. Chromecast is inexpensive and plugs into the HDMI and a USB media port on your TV. With a simple app download, this device allows multiple users to cast to your television from computer, iPad, phone, etc. My son is loving his, as he and a roomful of friends cast funny videos from their phones to his television to share. Imagine the possibilities in the classroom, as students cast from their Chromebooks to a large TV, sharing resources from the Internet, while you teach evaluating websites. Now if only I had an HD TV at school.......
