It’s certainly safe at this point to say that flash has won the war in the mobile space—I don’t think we’ll ever see another tablet or phone based on anything other than solid state storage. The war for the proverbial desktop (which includes most laptops) is far from over, with hard disk drives still outnumbering SSDs in most traditional computers. Still, SSDs are in enough places doing enough things that modern operating systems have changed to accommodate them.
I hadn’t really thought about SSDs taking over this way, but it makes perfect sense.
