You can choose not to ship the 99.

Shipping is part of the process.

Stated preferences vs revealed preferences.

Polling / focus groups vs sales.

You never really know what works until it works.

You choose not to ship maybe 90 of those 99, because it's obvious before shipping that they won't work. The rest you have to ship before it becomes obvious they're not that last blessed one.
