Alright, so, I have a macbook, with a 160Gb harddrive, and I need to upgrade it. Do you think it's worth waiting for 500GB drives to become avaliable, or should I just get a 320 avaliable now? I did some research, and I read that samsung released a 500GB drive, and they're "now shipping" although I can't find any place to order one, or even preorder. So how long do you think I will be waiting for this hard drive? And before anyone says that all that extra space is useless, I'm heavily into video editing, likes a wide variety of music (by wide variety, I mean I can fill up a classic iPod) and I also like to download movies and TV shows, by the seasons.
