All of these use cases ignore the "cooler" ("more practical," really) uses
of VMs, like zero-downtime hardware maintenance, instant backups, instant
provisioning, implementing enforceable security policies, and stuff like

Granted, server consolidation, increased utilization, and smaller hardware
maintenance budgets are attractive, but past those (compelling, to most
companies, it would seem) arguments, it's more about the stuff above.

Sorta like Linux and Apache aren't really the compelling applications of
open source after awhile... it's that they form a solid platform to do neat
things with... as it is with virtualization.
