In attempting (and succeeding, apparently) at humor, you hit the nail on the head. Magnetic storage, in its current form, can only go so far. At some point, the track of this technology will end, and we'll all be left stranded.
Except, a new technology is inevitably going to emerge before that happens... maybe this is it! We knock it now, but we may all be using this (or some derivation of it) sooner than we think.
And for a new technology, this pricing is pretty good. We'll see what actually happens, of course ;)
