How many times have people seen WoW used to show off Eyefinity? How many times have people seen people take the option of stacking monitors three high? In WoW, width matters a lot more then height.
But in using side-by-side monitors vs stacked monitors you are keeping constant the total number of pixels. Which isn't what we are talking about.
In the case of 1200 vs 1050 you are NOT increasing horizontal resolution you are _decreasing_ the vertical resolution while keeping the horizontal resolution constant, so fewer pixels in total.
Which is why the gifs above are not really honest - the image there is keeping the same vertical resolution and simply increasing the horizontal, which isn't actually what happens.
Someone might well consider the loss of vertical resolution worth it for the wider aspect ratio, but clearly that's a subjective matter of preference, and even 1050 fans would probably draw the line at using a 1920x1 monitor (i.e only 1 vertical pixel), even though that would be far more wide-screen still.
