Poll: How long will desktop computing matter?

Justin James predicts that the desktop computing model has five years maximum left for mainstream business use. What's your prediction about the desktop model?

The desktop computing model (and the client/server model) is in its dying days, with the exception of certain specialized applications, and a few holdout companies and industries that will stay with desktop computing for much longer than the mainstream. But for the most part, I feel that desktop computing is practically dead in the consumer space, where mobile and Web have become the norm. In the business space, I think most businesses have only one or two applications (other than Microsoft Office) which the bulk of their workers count on and that keep them tied to the desktop model.

I know of very few developers doing non-Web development for business applications at this point. I give the desktop model five years at best for mainstream business usage.
