I hear that. My T42 running ubuntu lasted over a decade, till I spilled a glass of water all over it. My brand new macbook pro has had nothing but problems with the battery recharging, and the headphone jack never letting the system speakers play, both completely solveable via software.
It may be obvious which of these console system seems more powerful, at least based on these leaks, but at the end of the day it's software that really matters.
Let's not forget the Wii:U is still in contention (though it's a bad example of lots of software atm), and its hardware is far less powerful than both Orbis and Durango.
It's the total package including h/w, s/w and intangibles (e.g., ecosystem).
H/w is important for longevity, peak performance, hard limits, etc.
S/w for the final user experiences, including the content and the actual performance.
I have my fair share of device failures, like my recent Acer 3D monitor that lasts less than 2 years. This is just a one-off sample.
Same for your example. Your MacBook Pro may also last 10 or more years. I think with Mountain Lion, you should be able to choose multiple speaker output, including AirPlay ones. Not sure what your charging issue is. Could be adapter related issues too. But yes, you won't be able to recompile your OS. ^_^. But you can install Windows or Ubuntu on your Mac if you so desire -- if you want different software.
This is where I hope Sony goes. If they want to include a general purpose OS and non-games in PS4, let us use low cost add-on hardware to run Android or Linux. Make it as painless as possible to integrate with other OSes like iOS.
Or do it via Gaikai. They can even let people choose their favorite OS + app services to run on the server in the future.
