I am teaching using more technology than ever before. I now have the option of having my students bring their Google Chromebook to music class.  https://www.google.com/chromebook/
Schools like this technology because it is inexpensive and gives every child the use of a computer.  https://www.google.com/edu/products/devices/.   Chromebooks are limited in their capabilities, but they are surpassing iPads sales to schools.  http://www.pcworld.com/article/2855768/why-chromebooks-are-schooling-ipads-in-education.html
