solBLACKIs the pole length the only difference? The one in the amazon.ca listing looks like it'll be cramped with a 27" monitor. Everything else looks the same though.
solBLACKThere is a option to switch to the "Monitor + Laptop (Standing)" version on the Amazon page that SnakeDr posted (http://www.amazon.com/gp/product/B00FOTABWY). It looks the same and is the same height, but the Massdrop one has an additional thing on the pole, shown under the top arm in the closeup picture.
