I watched the video talked about in this article…
HTC Magnum rumours rife following giant phone gag | Reg Hardware: “A group of self-confessed pranksters have admitted that their mock-up of a monster HTC tablet, dubbed the Magnum, doesn’t signal the manufacturer’s release of a super ‘pocket’ PC. However, the web’s now clogged with rumours to the contrary.”
And it became pretty obvious to me what I was looking at. I could be wrong, but the clue was that it came out right before the World Mobile Congress (formerly 3GSM) in Barcelona. If you were going to have a booth at a show and your product is very small, why not have a “blown up version” as a prop on display?
Unlike the massive iPhone’s in the window of Apple stores, it is neat that it is a fully functional version.
