The glass surfaces on the linked items looks nice - easy to clean too. I would make sure the shelf is high enough so that it doesn't take away too much work area, though. If you like keyboard drawers, mounting one might be a problem with it, though.
Well, the computer desk comes with a keyboard drawer...But my main system is a laptop at this point. I'm not sure I'd be using the keyboard drawer just yet.

Ease of cleaning will definitely be appreciated...I also like the "open" feel of the desk. The movable "side drawers" that are an option with the desk are something I'll look into getting. Perhaps a couple of those...
