I had to put some files from my USB ThumbDrive to iPod. That needed a Turn on, on my computer and then plugging things on, and a transfer.
I saw this innovation earlier. Wireless USB – Wireless Extension to USB. And also a USB Drive like product.
I feel this type of thing can be made for stand alone iPod, extra storage or archive. No need to turn on PC.
Also, i think, there may be a need (?), for a very small, tiny Wi-Fi Router with 100 GB storage, media and cache management. That can serve 2 or 3 iPods and 1 or 2 Netbooks.
