I give personalized flash drives at the end of the year. Teachers have to back up their files from their computers (we usually reimage them during the summer), and they come in handy.
I order from www.pexagontech.com and let my kids pick the color of the flash drive and what wording to put on them. You get two lines of text. We tried the ones with the swivel caps this year and I really like them!
My thought is that you can never have too many flash drives!
What a great idea!
