GPUs become obsolete way faster than monitors.

Are you trying to say Apple wouldn't put GPUs in displays because it might accelerate the display upgrade cycle?

[barrkel]

I'm trying to say that customers aren't quite stupid enough to invest in a display that they'll throw out 18 months later.

In a product line-up where a new GPU requires an entire new machine, merely having to replace a display would actually be an improvement.

Not that people with those sorts of interests, even when Apple customers, rely on Apple hardware to serve those interests.

As long as it can be used with a pass-through Thunderbolt mode, it would still be perfectly usable as a display/port expander without using the internal GPU, should you buy a faster machine.

Also, Apple stuff seems to last damn near forever, so it'll hold a lot of resale value (even if the GPU is two years old) for those who want to upgrade.
