This is great, if you want to stand while you work but don't want to be stuck in one place.
The only issue I have is that I do not like using the touchpad so I have a mouse, for which there is very little room.

Pros: Lightweight and mobile. For each hour you stand instead of sit you burn an extra 100 calories. If you stand during a full workday it's as good as going to the gym
Cons: It could use a bit more room on the top surface. The height adjustment tops out right where I need it (42") and I am below average in height (68"). So, they could add a few more inches to make it work better for taller people.
