seems legit

Templates are useful when application developers should be able to make low-level, detailed optimizations, like specifying if pixels should be 8, 16, 24-bit. Or even float/double, with/or without alpha.

While AGG is one of the most cleanest and high quality 2D rendering APIs, it's improbable that AGG will be accepted by the c++ committee, Herb Sutter works for microsoft, and AGG's author is very critical of many graphical features of windows, like the sub par font rendering. An example of this is the the dialog window for enabling high dpi font scaling.

No there is not enough bandwidth. 3x 4k 60hz screens use up all of the bandwith. That's why you either have 6x regular lowres screens or 3x 4k screens. The bandwidth is the limitation.

Next version of some display interface (displayport 2.0?) will even use compressed video because of bandwidth limitations.

The three thunderbolt2 ports should be used for 3x 4k screens, not storage. Then only slow usb3 is left.

No, it has 6x 20Gb/s thunderbolt ports. That's for the three 4k screens. Then you only has slow usb3 left.

Stop right there.

"literally" and "legitimately" are useless concepts in this case.

*legal* is the word your looking for.

In EU batteries MUST be separable by the consumer to make the consumer able to sort out different kind of waste when ditching the product, else the product is illegal. It's a shame Apple has been able to circumvent the environment laws with products so far. They tried, and in essence succeeded, with iPhone1, it had soldered battery, they had to change that, iPhone3 and newer has only glued batteries.
