Ereaders are great gift options for middle schoolers, but as parents, it's always disconcerting that tech gifts for kids are so pricey. Kindle has made both it's wi-fi, and 3G versions a little more economical with special offers options. In both cases, $25 has been cut from the price of the normal selection, through sponsored screen savers and other special offers.
Kindle wi-fi requires a wifi connection to download new content, and to use the web capabilities of the Kindle ereading device. Kindle 3G provides a free 3G connection, with no contracts or monthly fees. The ability to vote on screensavers through a Kindle App, Admash, makes it possible to impact the sponsored content.
