Why not make a USB storage device into the shape of a blank cassette?  That’s what the folks over Milktape are offering for about $15 and 128mb of space.  Doesn’t sound like much space by today’s standards, but it might not make such a dull impression when you need to send a label your demo or just give the gift of music for that certain someone who needs to kick back and unwind.

The milky cassette comes with its standard old school plastic cassette case complete with a j-card so you can scribble the track listings or doodle whatever the hell you want.  It might make your grandma actually think it’s the real thing, but when she sees the USB connector swivel open, she’ll need some understanding.
