I'm with you, at least as far as the consumerism is concerned. Maybe we are all fucking idiots, somehow, some way, but I tend to think if you've got a computer in front of you, whatever you're doing, you're in a mighty fine privilege. All computers have incurred their debt upon the planet; to dispose of a computing device because it is 'slow' is an ultimate failure to comprehend the nature of computing: the user makes a decision to use, or not use, arbitrarily.
I have a couple Toughbooks from the 90's, I'll probably never throw them away, but instead keep using them for more years yet, because: fully user upgradable.

Though slow by 'modern standards', they are still perfectly usable computers, still quite adequate for most needs, which haven't really changed terribly much. Slow-ass Pentium 133's with a nice, tight, Linux distribution, no driver worries whatsoever, and workable for my needs. One is an offline Wikipedia/Doc-dump that can be easily road-tripped, powered from a cross-bike battery, chucked up the cliff and so on, and the other is a general-purpose debug device for various embedded projects back in the lab, where-in such things as standard serial and parallel ports are still .. a bit useful ..
You know why these computers are still in use? They kick ass.
3 Open PCMCIA slots per device. Magnesium-Alloy cases that take a real beating, and can yet still be opened with a coin, in case you want to put a different component into the gel-protected insides. In the lab-bench toughbook there is room for its disk as well as various shields, arduinos, proto pcb's, and so on. It functions very nicely as a carry case in that regard, too: I have room for my DS-one scope, when I need it.
Oh, its got standard strap mounts as in I can take one off a gun and strap the toughbook behind me as I ride off into the desert.
If Apple ever make something like this, i.e. the complete other end of the spectrum, I would be very surprised. There are places, though, an iPad and a Macbook and an iMac and an iPod .. well maybe my iPod would fit along the DS-1 .. but anyway, there are places that the 'elite delicate consumer electronics' can't go.
My point is, there are alternatives to the Macbook cult.
Apple don't have ANYTHING that competes with the toughbook in terms of user servicibility, but then: that is another arbitrary choice being made by the Apple Super-power. Apple is so big now that if it decides to build a walled-garden, then such shall the field grow. If they WANTED to make a computer that could seriously benefit future generations, it wouldn't be out-dated in a decade, or two decades, or even three. It'd be useful for a Century.
