I am currently considering buying an external hard drive to store media on, and i think i want to dedicate it to the ps3 rather than suffer the quality losses from streaming. My question is am I able to copy files from my computer to the hard drive via the ps3? In other words, am I going to have to bring the hard drive to the computer every time I want to add something to it? Or can i somehow network the ps3 and pull the files from there...or transfer files from a USB drive to the external via the ps3 (to make it more convenient instead of bringing the external, power cable, etc. to the computer) Also, has anyone been successful in utilizing wireless N with their ps3?
