For those who follow other old computer hardware, here is a link to the iDisk for the Apple II. It's a card you plug into an old Apple II and load it with multiple disk images to run on the hardware. These images are stored on USB Thumbdrives and you can even add Bluetooth if you wish. It's still a work in progress and I found out about it from the latest Juiced.GS journal. Lots of fun and it's good to see products still being developed for the Apple II...
