Apple doesn't put HDMI ports in its products because it's too smug. All iOS devices use the 30-pin port, making it difficult to hook them up to an HDTV or external monitor. A special dongle can change that port to an HDMI one.
Sanwa's 30-pin to HDMI dongle solves the problem nicely. It lets you plug an HDMI cable from your iOS device to your display of choice. If only we cared. With Apple's AirPlay protocol officially in full motion and the hacking community doing amazing things with the software, who needs another dongle?
