Robert X. Cringley offers a theory about the Mac Mini: Apple will offer HD movie downloads a-la iTunes, and the Mini is the set-top box—complete with DVI to hook into your HDTV—to play those movies. Just like the iPod and iTunes did for music, the Mac Mini will do for movies.
I, for one, could see myself being a consumer of such a product and service. I would welcome the option of downloading movies if the cost and quality was comparable to a rental at Blockbuster. If the quality were to exceed that of Blockbuster—which HD would do until the HD DVD format war ends—it would only sweeten the deal. Does this excite anyone besides me?
