Yay! My antiPod arrived. Amazon took two weeks to tell me they didn't have any, so I went to MillerPC who delivered one in about 22 hours. It cost slightly more but I think it's worth it to be dealing with a company that actually has what you're trying to buy.
Argh! My work desktop gave me an electric shock when I plugged the USB cable in. Health and safety at work, rah!
Double yay! Getting the thing connected and working under Linux took about two minutes. Still slower than with a Mac, which was instant, but improving.
Double arse! The VFAT filesystem on the thing won't allow files with ? or : in the name. I have some renaming to do...
