I got my girlfriend an iphone. Now Iím looking at docks. Yeah I spoil her. Lol. She wants one that plays video. Iím having trouble finding more than just this one.

But it might be too big to lug around to show off at parties. I've had a couple ideas about getting a projector because I always see her and her friends huddled around her phone watching videos like its a campfire or they pass it around ten times like some proverbial doobie. I've seen a couple of brands online and was wondering if anyone has used any of these before.
