I decided to do away with my old metal & glass desk due to the lack of space that it provided, as well as the continual headache of cleaning the glass (slightly OCD here).
Oh Lord. I'm continually cleaning mine. If I'm not dusting the top, I'm spraying windex on it. usually once a day. My lamp seems to magnify any dust particles and finger prints or marks from my arms. If it didn't look good, and I didn't just buy the desk this summer, I would be getting something new also.
