i bought this autumn fall 2009 model last december. i love the red color and of course the brand itself, known to be a durable one. with mobile calls so expensive i opt to use skype to call my family overseas. however am havin a problem with the built in microphone. my usb internet cannot be use in an english laptop so my computer should be in japanese. now my problem is that eventhough the speaker is functioning i wasnt able to communicate since i dont know how to fix the microphone. need help!!!!
