I usually do wear polish, mainly to strengthen my nails a bit because they're kind of long and they'll break so easily if I don't have a coat of something on them. I just use my hands a lot for drawing, typing, and other outdoor activities and I usually end up having to file them a lot and all of that annoying stuff!
I don't like to wear any that is dark--I usually just put on the clear or light pink kind so they'll look more natural. The slight color and shine do help make them prettier, so I enjoy painting my nails, although I stink at it. XP
