Apple today officially announced their back to school discount program. Buying a new Mac for school will get you a $100 gift voucher for the App Store. It's not quite the free iPod they used to offer, but it's something. It will definitely buy you some music and a few useful applications for your computer. It's also worth noting that computers purchased for education are discounted, so it's worth checking out if you are in the market for a new computer.
Based on the education page of Apple's site, qualifying computers are the MacBook, MacBook Air, MacBook Pro and the iMac.
