Yes, the development is certainly great from the perspective of chemical engineering. And the development is useful from the perspective of information storage, particularly if large DNA is more stable or more resistant to free radicals than small DNA. However from the perspective of information storage we want smaller molecules not larger molecules.

From the perspective of DNA defect diagnosis I'm not buying it at all. Its all hype until they demonstrate how it would be cheaper than existing or in-development methods. I'm speaking as an individual who has managed a significant amount of DNA genotyping and sequencing. It sounds to me (at least from the press releases) that these are chemists seeking to find an application for what is a great piece of creative chemistry who have no awareness of the realities of the biotech market.
