hey! finally, ive bought the ST50 today!!! now for the questions: -if i were to use skype (video call), could i use a normal PC webcam? or do i require a specific webcam in order to use video calling... -also, how about voice input? could i use a normal PC mic? or do i require a specific mic? in order to speak on skype... -if i were to connect the ST50 using WiFi, do i need to buy a specific adapter to connect wirelessly? or just a normal adapter? thanks..
