TB seems to be the point where it's really the cut-off for easily available commercial hard drives. Everything above that, and it gets a little harder to find. And if you want to be perfectly honest, 1tb, or maybe 1.5 is the real, effective cut-off. You can walk into pretty much any big box electronics store and find a 1-1.5TB drive. 2 is a little harder, and throughout much of the country, it just isn't going to be sitting there on the shelf, because there isn't enough demand for it yet.
