well i dont remember who made it, but I used to have a glass desk and I HATED it. There are 2 major problems:
1)It's hard to keep clean since it shows ANY fingerprints or arm prints you make on it, so stock up on windex if youre gonna get one
2)I had one that had a smaller "shelf" that ran the width of the desk, but was positioned near the back. It was designed to hold a CRT monitor and speakers or whatever and it made it impossible to use the desk with a laptop. Basically, the shelf was in the worst possible place for using a laptop. If you sat the notebook right at the edge of the desk, it wouldnt allow you to open the screen all the way (Good viewing angle is about 120 degress from the keyboard, I couldnt get it to open more than about 60 degrees.
So, if you are getting a desk, be wary of getting one with a CRT shelf unless you check and you have proper clearnace for your screen.
