Only 3.75 lbs light, about 1" thin
Integrated 10Base-T/100Base-TX Ethernet and V.90 modem
Center Jog Dial?control and Memory Stick?media slot
NEW! 3 year extended warranty option(CTO only)
Optional SlimDock?docking station with optical drive for ultimate connectivity
Up to 850 MHz Intel® Pentium® III Processor

以上是在SONY USA上找到的资料R505的资料
国内站点索性找不到笔记本资料，估计和国内没有代理有关
我想Z系列可能是本土发行的系列。
