On the storage side, I can't help but wonder if it's partially due to incumbent vendors pushing flash as a high markup premium product. I suspect that I am not the only one who has thought, "Well, why replace this array with more already-obsolete magnetic disk that won't be any faster? Wait a year or three, flash markups will come down. Maintenance renewal is cheap."
Now, I realize that cheap flash is dangerous to incumbent pricing structures, so $100K for an all flash tray makes sense when it can replace 10 trays of $30K disk. So maybe they've seen no other choice, business model wise. Maybe it even makes sense to milk a once-per-generation technology disruption for all it's worth for a couple of years before commoditizing it.
But it has kept me happy with what I've already got, since the pricing of the alternative was, for my use cases, hilarious. As opposed to, say, this is somewhat more expensive but we can justify it.
