Well, take a look at this little baby, note the astonishing capacity, relevant to size, note the price tag, and then take a guess at how long it will be before that cost will be halved, and then fall rapidly to about 10% of what it is now.
I've left a couple of USB drives in computers before and lost them. I don't mind so much when they are only £5's worth but I would really cry if I left that one anywhere. Do they come with a security chain and a reminder alarm if you walk away without it????
