Hope away, sounds like you might need to lose a kidney to me though!
512mb CompactFlash is selling for $165.99 from Crucial. I don't know the margins, but let's say that the solid state RAM inside that costs $80.
That would make a 155GB disk cost $24,000! Or a 10GB disk cost $1,600.
Now my estimate as to the cost of solid state memory is a total guess, but can they really bring that down by a factor of 10, which is what it needs to make it even close to being realistically affordable for the average consumer?
