There is somewhat of a lock-in factor with storage virtualization, but it sure can be useful once you've got it. For completely non-disruptive data migration the work what would otherwise take months for a team of people can be scripted by one person and trickled over in a few weeks.
We're all irreplaceable until that time when someone devises a machine/process/alternative

SSD is not gaining traction simply because it's a buzzword and commands huge profit margins (both are true). It works. It solves real problems. In the right cases it saves money. If you spent some time in a larger organization I suspect you'd change your tune. You're comparing 2TB SATA apples to 256GB SSD oranges. Both may be fruit, but they're not interchangeable.
Agreed that SSDs have a long way to go on price to compete, but it's simply not true that they're not yet ready for the enterprise datacenter. All the larger enterprise storage array vendors (EMC, HDS, IBM, NetApp) say they're ready, and most are shipping them with decent sales. Despite their price and the "fact" you've so eloquently stated, you'll find them in many Fortune 500 datacenters simply because they outperform spinning disks by such a factor that they're cheaper per IO. I believe today the vast majority of vendors providing enterprise-class SSD drives are sourcing them from STEC. They play some tricks to work around write limits, but they've got ~5 year MTBF ratings.
I renewed my phone contract today; I finally have one with a camera. It also has a USB port for syncing with computers... which is disabled by Verizon (but of course they will transfer our files over their network for a low low fee).
