The premise behind this article is that the new CPU/GPU was late and did not make it into the iPad3, which is wrong as anyone who followed iPad2 rumors would know. The new retina display was late and did not make it into the iPad2, which is what caused that huge 8X leap in iPad2 GPU performance over the iPad1. The GPU in the iPad2 is massive overkill and a waste of margins, but the chips were already ordered and in the pipeline when the retina display that was meant to go with that chip was canceled.

Apple was facing a situation where retina was going to raise prices and restrict production, just as Apple facing an army of cheap knock offs, with tablet demand that was unsatisfiable. Going Retina in iPad2 would have surrendered a huge chunk of the market to Android, and made Apple a high end boutique player in the market they created.

There is a delusion that because Apple is a boutique player in the PC space that Apple would make decisions that lead to becoming a boutique player in other markets that Apple enters. Steve Jobs wanted the Macintosh to be cheap and ubiquitous, but market forces forced the Mac into the boutique space. Any other strategy would likely have failed given the volume differential costs the Mac still faces.

In the music player market the Apple iPod still dominates with ~75% market share, a boutique mindset is not compatible with long term market domination like this. Macs are just a legacy product that represent a tiny ~20% of Apple Inc's sales.

The iPad2 was ~$5 more expensive to produce than the iPad1 due to the 8X faster graphics and CPU upgrade to dual core. It faced cheap knock offs powered by phone chips generally slower than the iPad1, and saddled by Java overhead. The user comparison between iPad2 and it's competitors was embarrassing, Star Trek fast verses laggy slow unresponsive junk.

Even Apple's mistakes are working out for the best, sometimes you just can't lose.
