If you thought Zack Morris had a giant cell phone, get a load of this thing. The MegaPhone is a fully functioning phone that stands a whopping four feet high. You can dial by punching the buttons, but I don't know how you could possibly listen and talk at the same time. Even so, it's got functioning Bluetooth connectivity and USB ports, so you could always hook up a headset of some sort.
Sure, this is designed for stuff like tradeshows, but I would love to see someone try to make this their standard cell phone. It takes conspicuous consumption to a whole new level, not letting anyone miss what phone you're using. Totally awesome.
