As yet another nanotechnology takes the long walk toward market, Nantero's NRAM, some wise words are reported in the New York Times: "Flash memory is now so inexpensive, he added, that innovators will have a hard time displacing it from all but the most demanding applications even if they surpass it technically."
A similar situation exists with most competitors to silicon CMOS – it’s just so cheap and well integrated that it will probably be around for another thirty years. Nanotechnology will just have to learn to peacefully coexist for a while.
