Consumers want thinner laptops, and they want more powerful laptops. Something has got to give.
I don't disagree with you. But I do wonder how much of this "thinner, thinner, thinner" is driven by Apple themselves.
Here's why: If we look at the average thickness of other high end laptops like Lenovo's top ThinkPads, such as the T model, they are only 0.2 to 0.4" thicker than a conventional MBP. Yes, they are "business black" which some find rather boring, but they are purpose built to run cool, handle heavy loading under resource intense work, and still run quietly. That's why they have visible vents in the sides and back of the cases, and are just thick enough for excellent air circulation within the case.
In short, they are "Laptops", you know "Computers"... designed to do what computers do.
If Lenovo's priority for the T series was style... they could reduce the thickness by a tenth or two and still have a fast, cool & quiet running laptop. I've used them concurrently alongside of my Macs and the temps and noise levels are quite a bit lower than Apple's. Again I'm not being critical, simply offering an alternative viewpoint. I do realize that Apple likes to be viewed as an "innovator" hence if they build the "worlds thinnest" that's a bragging right only they can claim. Yet at what price? And I do not mean in currency, but rather in overall lifespan, clogging the landfill with remnants that cannot be recycled, et al.
The pictures in the iFixit article are beautiful. The MBP_R looks like a work of art. Components are carefully arranged, logically placed, incredibly close together. That's one heck of an accomplishment. Realistically, I'm as guilty as anyone, since I bought two sight unseen. Before the iFixit article. I trusted Apple.
And how do I like this model? It's fantastic. There's no two ways about it. I like absolutely everything about it... until I read the article and saw the pictures that iFixit published. It's just the thought of it being like the toaster in my kitchen. If it fails, you toss it. Not exactly "Being Green" as Apple began to advertise last year.
Oh well... I will certainly think twice before pre-ordering any new Apple product going forward.
