My top wish would be compatibility with Mac OSX. I'd at very least like to be able to add music to the NW series of players. I was very disappointed recently when I bought the NW-E507 and I couldn't even mount it as a USB drive, but other mp3 players worked fine this way. My old RIO even has itunes compatibility and mass storage drive compatibility with OSX. I use mp3's only for device compatibility. I finally got the NW-E507 to mount on OSX after backing up the device on windows and reformatting with fat32, but files were not recognized by the device. I always convert iTunes store purchases to mp3 for my Sony mp3 CD player, so I do not care about .aac at this time. Atrac is really out of the question since Connect does not even run on OSX and Linux. I reluctantly took my NW-e507 back to the store. I hope when the 2GB NW-E6xx comes to the US I'll have my dream mp3 device (usb drive sized mp3 player that has a radio, display, more solid than the shuffle, long battery life and it's a Sony. Sony, there are a lot of Mac users that are also loyal to Sony products, but you keep us from giving money that will help develop better Mac compatibility. If Sony made mp3 players compatible with iTunes there would be a another option for users. I can now play .ogg in iTunes through a quicktime plugin, couldn't this be done for atrac. I can access my Rio through iTunes using a Rio iTunes Plugin, couldn't this be done for Sony products. Obviously I can't use Sony Connect because I have a Mac, so give me another option or lose my business permanently. Sony, change my mind before Christmas or I will buy an iPod or Zen. I'll gladly write a stellar review on Engadget/MacOBserver if your product could at minimum transfer my mp3's to the NW-E6xx using the Finder and actually be able to play them.
