It's not quite Moore's Law, but a computer-related mark of time has just officially been passed. See that image to the left? It represents a $299 external hard drive. Nothing special right? No....except it's a full Terabyte of space: 1000 Gigabytes. Good god. Available now from Costco.
In my time of being involved with PC's, for that price, I have seen us go from drives measured in kilobytes, to megabytes (1000 kilobytes), to the current gold standard of gigabytes (1000 megabytes), and now to terabytes. Look for the new branding of specs that no longer come with tuberculosis, but the "new" TB.
