Those links are largely sensationalism. I don't agree with everything Apple does, but it's certainly not as bad as how those articles portray it to be. To call GateKeeper "DRM" is absurd, and having non-upgradeable hardware is a design choice, not a diabolical plan.

Unless you can show me a non-biased, non-partisan view of how Apple is the worst tech company to buy from, I'll continue to enjoy my MacBook Air.
