Pqi i810 series USB flash drives from Power Quotient are extremely tiny in size. They not much larger than your finger nail. But don't let that fool you they pack lots of storage space, the one that landed in lap was whopping 8GB. And they are cute and pink :) . The Power Quotient product page claims that these are world's smallest USB flash drives. However I didn't find any reference to this neither on Engadget nor anywhere else on the web.
At first glance its looks more like a MMC card than a USB slot. It really felt strange to plug it into my USB drive. Like most exotic hardware I thought it would be a pain to make it work with gnu/Linux OS. And Surprise, surprise it worked just fine on my Ubuntu Jaunty 9.04 laptop.
