SONY VAIO P claims that it can fit in your jeans pocket. Fine. But, can you walk properly with it in your jeans pocket? Well, you can walk but not too comfortably. The VAIO P will keep sliding out when you walk.
Here is the ad SONY is advertising in Japan, which shows a girl in low rise jeans carrying a VAIO P in the back pocket.
And here is another video, not by SONY, but by Gizmodo Japan.
Also, it is not a good idea to carry such an expensive machine in the back pocket. Is it? ;)
