I can't find any cons. It's a really nice desk. There's 25 pound weight limit but I don't ever have more than that on my wooden desks any how? 25 lbs is quite a Bit of stuff. a computer screen 5, keyboard mouse 2 lbs. printers don't weigh much either. 

BUT If u want the pivot side on your right? You'll not be using the legs they say to in the instructions.

You'll be using the legs they show in the instructions which are needed for the non pivot side instead, so this way the pivoting desk now has the capability for its left side to be fastened with the corner hardware.

Just plan carefully otherwise you'll be taking stuff apart or just dealing with the pivot being on your left.
SO TO CONCLUDE
the makers of this darn thing NEED to provide a seperate instruction for purpose of the opposite orientation.
