Here’s great article about the ideological path from open computing to computing appliance and the two Steve’s of Apple that were at the vanguard of pushing both ends of that spectrum:
Steve Wozniak, Steve Jobs, and the long road to the iPad. – By Tim Wu – Slate Magazine.
I have long contended that computers have the same trajectory as automobiles. Initially the domain of cutting-edge enthusiasts, moving through eras of: mass-production (Model-T v. IBM PC), large-differentiation (trucks/cars v. laptops/desktops), into customization (hot-rods v. case-mods). Eventually, the car market evolved into what we have today, a highly commoditized market were owners are are unlikely to tinker with the vehicle and depend on specialists to maintain and repair their car. Rather than increase the performance of their car through tuning, adjustment, or upgrades, consumers choose to just purchase new cars. The same is probably now true of computer users as well. It has been common industry knowledge that a segment of the population only upgrades operating system by purchasing a new computer.
As a thoughtful and long-time computer user, I applaud the design and functionality that modern Apple products represent. As a long time computer enthusiast, I bemoan the increasing commoditization of computing. As a computer science researcher and educator, I worry over the fact that our students seem to be increasingly the former rather than the latter.
After more than 20 years as an Apple user, and well over a decade as an investor, it’s articles like this one that have me considering dumping my stock:
I’m still tinkering, but I pretty much just finished my first iPhone app that’s more interesting than a list of text.
