This thread is to post secrets about WDW that meet two criteria:
1) You yourself, or someone in your party, found it out during your trip. Basically, you were there when it was discovered.
2) It's not common knowledge amongst Disney fandom (i.e. no "Did you know Everest has no backside?")
If anyone wastes their time by going to that House of the Future thing at Epcot's Innoventions, where you have Home Theater PCs, hybrid SUVs, and other emerging tech hustled by a CM, take a close look at the HP tablet laptop in the "girl's room." It's the one where the CM supposedly writes a hand-writes note on her blog using the tablet PC's touchscreen, telling her to do her homework.
When the crowd moves across the walkway to look at the other things, get a close look at that tablet PC. Chances are the CM will leave it right where they found it which means if you have normal vision you can see it pretty well from the guardrail. For all I know, you may be able to ask for a closer look at it, and they may oblige.
If you look nice and close, you'll notice it's running MacOS. Sort of. The whole screen appears to be a full-sized Flash animation. At least, that's what I'm betting it is. That's the only thing I could think of that would fill the screen, animate the "web page" on screen, and have that level of detail. And for whatever reason WDI designed it to look like a Mac screen even though it's on an HP PC.
Also, the web browser "throbber" (the thing that animates while loading a page, like the spinning E in explorer) on that screen is the old EPCOT Center "nucleus" logo.
