Apple makes great computers, and Steve Jobs is started three technological revolutions. The fist was to make a desktop personal computer. The second was to make a portable digital music player, and the third was to make a portable computer that fits in your hand (iPhone). Each revolution has changed its respecitive industry (computers, music, phones).
The iPod is a great tool for education. You can load audio, and even video on to an iPod and it becomes a portable media machine. It works better than a CD, cassette or MD player. You can bookmark places in your sound files to go back to the exact place each time. Get the AV cable to connect to speakers and digital projectors.
