Of course, the business logic must be coded in the operations, but no UI code is required to construct a fully functional prototype.

当然，必须在操作中对该业务逻辑进行编码，但是要构造完整的功能原型，不需要编写任何 UI 代码。

In contrast to the functional prototype you would typically build in step 1, the evolutionary prototype covers the full breadth of architectural issues.

与你在步骤1中构建的功能原型相比，这个进化的原型覆盖了架构问题的所有方面。

The dedicated folks at webOS Nation have managed to get their hands on a functional prototype.

They are all in an acceleration program that pushes them create or improve their functional prototype and acquire their first users in six months.

Of course, the proof is in the pour, and the video below (produced with a fully functional Nomad prototype) demonstrates the True Crema Valve and shows us a delicious looking espresso shot.
