Shouldn't we end up "connecting" an external graphics processor rather then "inserting" it? Insertion feels like putting something in, usually resulting in the thing being inserted becoming internal to the thing being inserted into. I.E. disk (compact, hard or floppy), making the beast with two backs, a bookmark, sample for the test chamber.

With external graphics dojiggers I envision us have large boxes sitting on desks hooked to our computers and even more fan noise due to power and cooling needs.
