I think the first company that builds a laptop that's easy to work on, and can guarantee supply parts for, at least 7 years, might be able to win over guys like me--who want consistancy? I want to turn it on, and do work. I don't need the fastest chip. I do want to be able to work on the devise myself. I am older, but never understood this weight thing--make it out of metal(Aluminum is fine. Use the case to disperse the heat--great! I don't care, as long as I can take out the screws, and put them back in, and they don't strip.) I have seen so many products start out great, but get too fancy. So fancy, they don't work? And can't be repaired, reasonable priced, because of the Fancyness? (Don't get me wrong, I'm still a fanboy, but they are loosing me with every new upgrade, and model.)
The answer to this is a resounding "no".
Other unibodies have been okay, the retina MBP being the best so far I find at even heat dissipation.
