> As a keyboard manufacturer why would I listen to Microsoft? Why would I add a key that supports a product I see no benefit from? As a keyboard manufacturer, you don't have to see any benefit from the product you support. The question is only will the incremental costs be more than offset by the incremental gains in sales. If MS requires the key, that's 90% of the market (really rough number), so it makes sense to add it. If MS and your competitors add it, it may make a significant percent of your customers go elsewhere. Even if they don't want the key, just because they think your keyboards are old.
