My X505 is japan CP model, without wireless card and USB mouse, but got 1.1G and carbon fiber. Personally, I do not care about the USB mouse, because I do not habe memory stick and I hate the cord with a mouse. I did want the wireless card, but it was not included in CP package. I used to use the Belkin 802.11 b/g card (54Mbps), it worked fine, but stick out from my PC card slot.
When I saw the PCWA-C800s (108 Mbps) on Ubid.com, I bought it at once at $56.00. And received it today. So far, everything worked fine. I got pretty strong signals with this C800S card, much better than the Belkin card. But I do not have the 802.11a network, I can only use the 802.11b/g function. But it is very easy to switch between these 2 networks, or use them both if you have. The utility is good too, you can turn off your card by right click in the system tray. My only complain is the color. PCWA-C800S is white, I guess I will paint it to black someday, maybe this weekend. :D :D
