Apple loves to canibalize itself. iPod, which used to be 50% of the company: practically gone, totally canibalized by the iPhone. The iPad has already eaten plenty of Mac, outselling it between 2:1 & 3:1. The idea that if only the iPad were less locked down it would sell more and canibalize the Mac, thus Apple doesn't allow it, is absurd.
The App Store "tax"? Sure, Apple doesn't mind the cash. But they are first, second and third a hardware company: that's where the real money is. The reason they have no intention to allow side loading apps on iOS has to do with user experience, eliminating support headaches and security (order may be different, but these re the reasons).
The fact is your dream device would appeal to the same people who buy desktop Linux machines now. They exist, but they are a tiny part of the market. Nobody can stay in business catering to just those customers.
