I think it will happen much sooner than that. Flash doesn't have to match the price/GB of hard drives, it just has to match at the minimum viable system level.

I think it will happen much sooner than that. Flash doesn't have to match the price/GB of hard drives, it just has to match at the minimum viable system level. A lot of people could survive with 120GB, and that number goes up drastically when you hit 240GB. When the price of those SSDs reaches the hard drive floor of about $50, hard drives will become a niche product appealing only to those who actually need multiple terabytes.
