Happy New Year!
The cable came in yesterday, and I tested it this afternoon. At full extension, the cable is a bit over 2 feet long. The extension and automatic retraction were smooth.
I use a MacBook, and run Windows XP in a virtual window using Parallels. The cable worked fine in both Mac and Windows. I was able to transfer a file to the 505 Reader using the Sony software in Parallels, and I could look at the Sony as a drive on the Mac side (OSX 10.4.10).
I travel a lot, and have wanted a retractable cable to help lighten my load when transferring books on the road. This cable will be perfect for my needs! Organizing my power cords for travel is a 2009 project: I have been reading older posts on this subject, and just need to choose a solution
