You are a seriously disagreeable person. Not because of your argument, but your entire attitude and personal attacks. Frankly you're an ass.
Nobody is saying that a product is immediately profitable the day it springs forth from someone's creative mind. But that's beside the point, and if you weren't such a clueless self involved ass, you'd realize it. AT&T didn't kill off it's nascent answering machine because it couldn't be profitable, they killed it off because it was a threat to their phone business. They killed it off, in fact, because they felt it would be profitable and popular.
As for your example, of how stupid you are, Toshiba didn't invest in flash as a hard drive replacement. It was a portable storage medium for cameras, as well as chipsets soldered onto boards. The idea of flash hard drives only became feasible in the last decade or so, but flash has been a profitable business venture for Toshiba and other companies long before technological advances allowed it to be used as a hard drive medium.
For that matter, early mechanical hard drives were not exactly impressive by today's standards. The first hard drive was created in 1956 by IBM, it was the size of 2 refrigerators, held 3.75 Mbs of data and IBM leased them at $3,200 a month, and made a nice profit off them for 13 years. So half a million dollars in revenue each over their lifespan and people were happy to have them! You braindead moron.
