Amazon's Breakthrough E-book (BusinessWeek)
Every e-book reader released to date has failed, and this reader (manufactured by Amazon.com) may very well follow that trend. However, I'm convinced that something similar to this will eventually prove to be the "killer" convergence device -- one that causes you to abandon a number of other devices. Its size and weight, its seamless integration with the Internet via the cell phone data network, and its non-eyestrain-inducing screen ("electronic paper") are key features of what should eventually replace the laptop computer.
