Doesn't seem like it should be just a "niche market" to me. As they dig deeper into the genome (human and other organisms) the importance of a correct read will be ever more important.
Some companies are now looking at areas of the genome previously thought of as junk DNA. Not junk at all they are finding out. As they wander out into these obscure DNA areas - won't a longer read become just that much more important? Having missing sections or gaps is like having a manual for an important instrument with pages missing.
