So Wired published an insightful interview with Amazon's Founder Jeff Bezos, discussing all things content consumption, cloud computing, consumer culture disruption and an odd side-track about his financial pledges into public space travel. The bit that formulated opinion is where he starts to discuss the Kindle Fire as more than just a competitor to the iPad.
This pushes forward the two competing concepts of how computing should be done, aforementioned in the title. The Post-PC device, as predicted by Steve Jobs and the general trend of products from Apple is to be the new "car" when Personal Computers become trucks. On it's lowest base: Post-PC devices rely on new input / output methods and allow a new population of non-expert users to use the product more cheaply and simply. There is a focus on the OS, the experience is centralised around the device, and content is downloaded to the device.
The Post-web device is something that is best demonstrated by the Kindle Fire: a culmination of the services that Jeff has accrued over his illustrious 15 years. Taking the concept of computing up into the cloud, streaming media, taking the focus off the OS and the hardware, instead forming a more literal definition of a window to your content.
This has presented two interesting concepts for the future of computing, both have a bright future for sure; but which would be of preference in a world where many only choose one?
