A friend of mine bought a netbook several years back-I think around the time he started college in 2008. It served him well, especially since he had a gaming PC he'd built back in his dorm room. I never used a netbook since through college I used a full-sized 15" laptop for everything, but I always thought the format made a lot of sense for someone like my friend who had a full-blown computer to back it up.
My friend loaded a lightweight Linux distro(maybe Puppy Linux, although I couldn't swear to it) on that particular netbook 3 or 4 years ago, and his then girlfriend used it. He and that girlfriend have since parted ways, but the last I heard she was still using the netbook.
