The first one by Exkild is a full and detailed explanation of all the new magical features of the new 27" device. My favorite part of this 6:45 tour is expaining the new features in iTunes which will automatically download good music, delete bad music and if it finds a song by Justin Bieber, it self-destructs.
The second one is a 1:45 action movie opus made by Evan Larimore, a guy who is really into movies. A huge iPad2 with the eye of HAL from 2001: A Space Odyssey descends from space and wreaks havoc in the hand-held style of Cloverfield.
Take a look. They're bound to give you a chuckle or two.
