128GB SSD models sell for, on average, $225 while for that price you can purchase three 2TB HDDs. Certainly the average consumer would prefer 6TB of storage to a measly 128GB for the same price.
Over the past two years, however, SSD prices have marginally fallen, while capacities have increased thanks to better manufacturing processes.
Gartner says it expects SSD prices to fall to about $1 per GB next year, still not "cheap" but certainly more affordable than current prices.
