Which Linux distribution packs the most punch?

System builders considering a Linux desktop are faced with a dizzying array of choices. There are dozens, if not hundreds, of Linux distributions to choose from. Narrowing the field of contenders basically comes down to what works best for both the system builder and its customers.

Finding that fit often leads system builders to pursue a commercial distribution over an open-source one. Today's commercial desktop Linux distributions make a lot of sense for system builders, mostly because of three factors: recurring revenue, licensing and support.
