I recently read a wikibon article I must have missed two and a half months ago when it was published. Scott Lowe wrote IBM’s FlashSystem Isn’t For Mainstream CIOs…yet . In summary he appreciates IBM's efforts to drive flash technology forward but he clearly sees all-flash arrays being in the early adopters phase and only interesting for special clients with special workloads (other than "mainstream CIOs" ). The world doesn't seem to be ready for flash.
But it really is.
