John Gruber wrote about why Google employees don’t use Google Glass.

If Glass were a good product, people who have them would wear them. It’s that simple. Same with tablet PCs — the problem wasn’t that Microsoft employees wouldn’t use them and that the product thus lost momentum and didn’t catch on with consumers. The problem is that tablet PCs were crap products.

When your own employees don’t use or support your product, the problem is with the product, not the employees.
