I also had problems before with a sony discman and a sony cd for pc.
I will never buy Sony again. I am also in South America so offcourse I am fu**ed for life. We latin people don't deserve same treat as our North American fellows. And it cost me 350$ to buy this expensive crap that worked a year!!!
If there is a solution please tell me, I am planning to build a hate site for Sony, anyone wants to join? Maybe if we send a petition to Sony all the n707 users together they will refund us or give us a new MD?
IPOD here I come (when I have the cash...)
