I would use this portable projector in my classroom. You can hook up an iPod, iPad, iPhone, or laptop computer to this portable projector. So if you are teaching a lesson and have something saved on any of those devices and you want children to see an image on a device you can plug it in to the poratable projector. You can carry this portable projector anywhere with you.
Iphone video projector a really cool idea for those who live with their iphone, iphones are becoming even more multi functional, soon we wont need any extras as the ihpone will do it all. this also charges whilst projecting which is a big help.
