Of course, lower cost is almost always better.

But just because advanced devices with (currently) costly components have higher costs is no reason to not create them.

If something works and meets a need, the costs of components and manufacture usually come down as engineering and manufacturing progresses on the learning curve and competition comes into play. (Not true when there is a captured market where extractive pricing becomes the norm, but those are the exception in consumer goods)
