While inheriting the basic functions and design philosophy of the current PlayStation 2 (SCPH-50000), the internal design architecture of the new redesigned PlayStation2 computer entertainment system (SCPH-70000 CB) model has been completely overhauled, resulting in a slimmer and more lightweight form. Internal volume has been reduced by 75 percent, overall weight has been halved, and thickness trimmed down to 2.8 cm (thickness of current model is 7.8cm). Its size is almost as small as a hardcover book, making it easier to carry around. Equipped with an integrated Ethernet port for network gaming, the new PlayStation 2 sets new standards in the fusion of design and functionality. Approximately 40 percent of North American PlayStation 2 online gamers use dial-up connections and to satisfy this base, the North American model is equipped with both Ethernet and modem ports.
