Other issues come from the need to place the nanotubes in extremely precise locations to get any electronics to work. We haven't figured out how to get them to grow in any particular location, so scientists have had to make them separately and then let them settle onto surfaces. Unfortunately, this process generally creates a thin film of randomly oriented nanotubes, ｛punctuated by aggregates｝ where large numbers cluster up. And there will be a few randomly placed metallic nanotubes lurking within the film.
