EDIT: Anybody can now buy a good 256 GB USB thumb drive for under $35.
I thought, "Crazy ol' Geek got his figures wrong again!" so I did a quick Google, and you know what,
you're right! Here in the UK I see a 256 GB (USB 3.0!) pen drive for 27.99 UK pounds, that's 36 USD approx. Wow. I was give an unwanted 320 GB hard drive by my boss at work, I was going to buy a USB 3 enclosure for around that price. I think I won't bother.
