I've had this plant for... wow, probably five years now! The leaves do tend to be much darker and/or more purple than my other orchids. It may be getting more light than before, considering it's near the cattleyas, which get artificial light. Maybe the damage on the leaves could be sunburn?
SFLguy - thanks for the ID! Now my orchid has a name other than "the little pink one that gets lots of flowers".
