How much can you evolve a USB flash drive to make it saleable? Just check out the Aroma USB which is currently selling at USBGeek. As the name goes, it disseminates sweet fragrances of Rose, Peppermint, Jasmine or Lavender when plugged in. It comes with fragrance oil and costs just $7 for an unspecified storage space (I presume to be a gig). But wait, storing data is not its USP.
