Absolutely. Also, much software out there is pretty much optimized for
single cores. The software that DOES that advantage of multiple cores
usually ends up performing quite a bit better, but rarely at the core
count (i.e. 2X cores resulting in 1.9X speedup, 4X cores, 3X speedup).

The multitasking most people do helps utilize multiple cores even with
single threaded software. But the fact of the matter is for most users,
all they need for MOST of the time is a single core.
