Sony's Vaio P was amazing that every geek out there synomously explains as a terrible mistake. Other than the factually "pocket-able" size, it had the interiors of an underpowered netbook and a resource-hungry Windows Vista to create things inferior. Also, there were way too many pixels packed in that small screen that complete text seem like tiny ants.
This year we've seen that "thin" is the USP that corporations are focusing on for their premium segment products. Have a watch the Dell Adamo XPS for example. Thus, the race for ultra-thinness and the most lightweight continues.
