The dongle has received a lot of bad press among sample enthiasts lately. They're instrusive, inconvenient, some are crackable, and they are ugly.
Maybe if they were cute or delicious they would gain wider acceptance. USB drives can come in many shapes, designs and colors and these designs can be adapted to sample/DAW dongles. Perhaps some of these from Japan will makes dongles more appealing:
The Sushi dongle
The Shrimp Dongle
The Thumbdrive Dongle
The headless Barbie Dongle
