Your language aside..
Of course an SSD will be better than HDD. That's a no-brainer.
However.
Will it be better once price/GB is considered? I'd say no, depending on the SSD of choice. I don't think we'll ever reach a time where we'll be totally independent from mechanical drives (.. if price at all matters).
In a few years, the SSDs availible to the masses might reach the capacities of current mechanical drives. But for the current SSD-prices? 10x more?
And how far ahead will mechanical drives be in storage/drive at that point?
