I bet those vaporous people you speak of with 80" tv's are sitting far away from the screen if they can't perceive the difference... Either that or they are the same brilliant people who can't tell the difference between low-def and high-def.
There's no point in arguing about something so subjective. If a 2880x1800 15.4 inch display is worth the $howevermuch premium to someone, then none of us can dispute that.
With that said, it's not worth the premium to me; nor is any Apple product. But I'm a function over form kind of guy.
Personally, I may be willing to pay a $200-300 premium for a display like this if offered for a product I might otherwise buy--a list that does not include a Macbook.
So, you seem to have contradictory points there. If you prefer function over form you should like more pixels... Form would suggest that you would want something just for its aesthetics. More pixels IS higher function btw.
Retina MacBook Pro Pushes the Limits of its Graphics Capabilities - Mac RumorsWith the integrated Intel HD 4000 and discrete NVIDIA GeForce GT 650M graphics units responsible for driving 2880x1800 pixels in standard Retina mode and as many as 3840x2400 pixels before downscaling to display 1920x1200 at its highest non-Retina resolution, Apple is clearly pushing the limits of the machine's graphics capabilities.At the default setting, either Intel’s HD 4000 or NVIDIA’s GeForce GT 650M already have to render and display far more pixels than either GPU was ever intended to. At the 1680 and 1920 settings however the GPUs are doing more work than even their high-end desktop counterparts are used to.
AnandTech goes on to assess this graphics performance, noting that the Retina MacBook Pro at times struggles to maintain a "consistently smooth experience".At 2880 x 1800 most interactions are smooth but things like zooming windows or scrolling on certain web pages is clearly sub-30fps. At the higher scaled resolutions, since the GPU has to render as much as 9.2MP, even UI performance can be sluggish. There’s simply nothing that can be done at this point - Apple is pushing the limits of the hardware we have available today, far beyond what any other OEM has done.
Focusing on browser scrolling behavior, which also involves substantial CPU load, AnandTech notes that the resource-intensive Facebook news feed pages can display at over 50 frames per second on a 2011 MacBook Pro, but that the new Retina MacBook Pro struggles to hit 20 frames per second as it pushes so many more pixels.
