More than anything, I'm amazed and dismayed that tablets are far surpassing the screens they put on laptops these days: http://www.google.com/nexus/10/ - why won't anyone who's not Apple make a decent screen?! They've gotten worse, as my current machine does 1920x1200, and you can't find those anymore.
Windows 8 does have better handling for high DPI screens, so hopefully we will see some higher resolution screens coming out over the next year.
I also blame the "HD" moniker. My rant on HD: http://tiamat.tsotech.com/hd-sucks
The perception in the non-Apple segment of the market is that the customers will not bear the increased cost.
A $250 laptop will last you 6 months while a $1000 laptop will last you five years, but there is still the market who finds a better deal in the incredibly shitty computer.
Higher price points let them include higher specs, even on non-obvious pivots like pixel density and overall build quality.
Also worth noting is that 1920x1200 is less dense than the Retina displays.
So you'd expect it to cost less.
I run Linux, and I am not interested in MacOS X, even if the hardware is nice. It's not a good fit for how I work.
$1000 is the high end of the Windows laptop line, and gets you just as much as the $2500 Macbook. But you're right, when you hit that price for Windows laptops, people sometimes begin to balk and move to Mac, for one reason or another.
Other companies are catching up (have caught up?), but relatively poor scaling in Windows 7 made it more difficult. Windows 8 still has the same scaling issue for desktop apps.
(As an aside, my Dell laptop runs Ubuntu and keeps the Windows OSes caged in VMs... :) )
Nokia is different - Microsoft wasn't displacing a successful smartphone business, they bailed out a massive clusterfk. Maemo was promising, sure, but in no way profitable. Basically, Nokia wasn't in a place financially to make a long bet on a new player in the smartphone OS market - Microsoft was.
But if so, would the other board members care either way about Ubuntu/Linux?
And even if they do they could give in on this to get something else.
Of course they would care if it brings profit.
In my experience, the vast majority of such devices are wiped and loaded with pirated Windows.
Until they start enforcing copyright protection, quality software alternatives will never get the boost they need.
