You ever get that watching a video on an iPod or iPhone just isn't cutting it? A know-it-all would say, "Well, that's what you get for downsampling the video to fit it onto that little thing in the first place."
Ha! Pity the fools with logic. We don't believe in such magical tales - we've got a much better option; how about projecting the video onto the big screen again via an iPhone Projector? It might not be as pocketable as your iPhone, but still, that'll show 'em.

The iPhone Mini-Projector is by made these guys. The website's located in Taiwan, so I'm guessing eBay or direct purchase through a manufacturer inquiry is your only option if you want the power of a portable iPhone projector in your hands.
