Your Z can connect to your PC with no fuss if you use the USB drive feature.
Goto the settings tab, tap on PC Link, select \'Storage\' and use the drop down menu to select between CF or SD. Tap OK and you\'re done. Just plug into a PC, it should recognise it as a USB Mass Storage device, you may need your CD to install the drivers under windows, i don\'t know. Connects to my Linux PC like a normal disk drive, good stuff!!
Enjoy your new Z!!!

BTW I think the standard Japanese ROM is 1.20, I might be wrong, I flashed a new ROM within 12 hours of getting mine. I highly recommend the Cacko ROM if you want an all English device (and ogg music playback).
Also BTW, if you do use the USB drive, I switch it back to \'PC Link Setting\' after use or I forget and it can cause me problems later.
