I take a lot of pictures when I'm traveling and like to preview them on a PC before I get too far down the road and find out they aren't coming out as I had thought. As such, I always take along a card reader - even if I have one built into the PC. You never know when you might want to share with someone else who doesn't have a reader or maybe you simply want a back-up with you. However, I also like to travel light. Apparently, Kingston had people like me in mind when they designed the MobileLite G2 USB card reader.
