The problem is that nVidia somehow screwed up on OpenCL performance with their Kepler GPUs. But specifically just OpenCL.
The more cynical view would be
"Nvidia deliberately screwed up on OpenCL to lock people in to CUDA".

there is always a reason for two fansHas there been any talk on how internals would be redesigned without a dGPU? Presumably there would be no real reason for two fans, nor for the metal connector that you see between both heatsinks in the teardown guide. Seems excessive, and the added space could be used for something else.

i think was better and perfect for apple to include HD5200 in 13" rMBP and for mac mini with i7 model and keep the HD4600+dGPU for the 15"
If they don't include dGPU than i go for the 13" rMBP with 5100...form factor better/lighter and not so much difference between HD5100 and HD5200 for the extra room/money etc
My plan is to sell my current 15" rMBP to get the Haswell version, even if it doesn't have a discrete GPU. In my experience, the gpu switching isn't very reliable and will often switch to dedicated for tasks that it doesn't need to, eating up battery life. Also, when I bought the current model my plan was to use it as a gaming machine as well, but I found that it wasn't able to run the latest games as smoothly as I wanted even on modest graphics settings, so I ended up building a dedicated gaming rig. With that in mind, I really only want discrete graphics if they truly are powerful enough for gaming, otherwise I'd rather take the latest integrated and have improved battery life.
However, I completely understand that not all graphics work is gaming related so I'd understand if some people would be miffed to not have dGPU. I'd say it's a tossup and that it would be good for some and bad for others, you can never please everyone.
Mavericks fixed graphics switching. That's how it improved battery life so much over Lion and Mountain Lion.
It's up to you whether you want to take a significant hit to your financials in order to get a new machine (and lose out on graphics performance), but personally, I don't think it makes sense... as the gain in processing performance is minimal (unless you encode videos a lot), but the loss in graphics performance is noticeable, and all the while the gain in battery life wouldn't be significant because the screen still sucks far too much power.
One reason if they ditch the dGPU I will get a Ivy from the refurb store when Haswell versions are out they should be even cheaper then
What other uses would be affected by a lack of dGPU?
