The latest laptops and cell phones offer the kind of unprecedented connectedness that even James Bond would admire. Chip speeds, network improvements, and design innovation are driving spectacular growth in digital capabilities. Where the smallest devices once commanded premium pricing, now smaller is often cheaper.

A sign of the times: More laptops are being bought by consumers than ever before. Desktop computers are becoming commodity products, with prices as low as $300 for speedy models.
