Query: Great tables, very practical

I love these tables, they're very practical and can be used in a lot of situations.The best part of them is the way the legs are shaped. That L shape allows them to slide under most couches or beds in order to get surface closer.The adjustable height and incline are very convenient.The only problem I have with them is that the cup holder is pretty useless (I leave mine in all the time) and that the surface of the table tends to bend. So it's not a good surface for mousing.
