suggestion ng officemate ko, yung mga mp3's and other downloaded files pwedeng i-transfer sa memory stick (not sure kung yon ang tawag). yung pang usb. i'm not sure also kung ilan ang kayang file na i-accomodate. someone in the previous replies said that you can upload these downloaded files back sa internet and then download it when you're settled in your destination. kung maiwasan po ang pag-burn better.

yung sa ipod kasi obvious na pang personal use, yung laptop ninyo pang personal din. applicable siguro for both. do not bring lang yung mga pirated copies na cd's/dvd's.
