4K is for programmers

I don't think we're anywhere close to the limit where something like Eagle Mode won't still benefit by adding more pixels (provided you can also supply the memory and processing capabilities for it to work responsively). The same kind of thing could apply to many tree structures, or graphs of complex relationships - being able to visualize large collections at once without the context-switch of scrolling is useful. Being able to view the whole source code of an application at once would be incredibly useful.

Another example might be reading or writing some research paper. Frequently you end up scrolling back and forth through a paper to cite or connect the bits together, which is pretty cumbersome, particularly when "back" buttons don't always have the expected or desired behavior (e.g, many viewers are missing a "push my current scroll position onto a stack before navigating" feature). Being able to view a whole document at once would ease some of that.

It'd be interesting to see some studies on the difference between the efficiency of using spatial layouts compared with sequential actions. It seems to me that spatial layouts quickly become rote actions that don't require much thought, but having to execute a set of commands is repetitive and error prone. (e.g, how many times have you clicked the wrong application in a task bar accidentally when you have a brain fart?).

It seems the industry is obsessed with heading in the opposite direction. I find mobile platforms a pain to use and I generally avoid them. Things like Gnome Shell's task switcher are also a regression from task bars, as the sequence to switch an application now has extra steps.

Yes, you can buy a wonderful, physically adjustable, mountable, color calibrated, blissful contrast, delightful brightness control monitor with a great matte finish like the Dell 3014... or you can buy an absolutely awful 30hz, locked in place, blue tinted, horrible uniformity, terrible brightness, awful contrast, with horrible black levels and really -- just horrific to work on 4K "tv". I speak from first hand experience, it is absolutely one of the worst panels I have ever had the misfortune to stare at vim on.

The colors are so awful that literally, some of my favorite themes (seoul256) where ENTIRELY unusable, just a greymush of nothingness. With bright spots and dark spots to make reading code even harder. So, I tried a black background theme... only to be horrified with the black level.

I agree with the author there is no comparison, obviously almost anything beats the Seiki. Hell, most review sites won't even recommend it as a TV, let alone a monitor.

People like to have their TV on all day long: with a projector you can't, because it won't be very visible in daylight and it will burn through lamps like it's popcorn.

Second point, modern TVs usually have a tuner in, you plug them in and they work. Also you don't need to adjust the image until it's rectangular.

You don't need to have a line of sight for a TV, chairs and people are not an issue.
