Ordinary perfboard suffers from a couple of problems… First, it has no groundplane, so there’s nothing to prevent excessive radiated noise. Also, today’s parts tend to have much higher density leads, meaning the holes must be drilled closer together. The added groundplane and plated through vias also will aid in heat dissipation by acting as “chimneys,” as if often done with high density surface mount power devices.

NOTE: This was an April Fools joke.
