Have to disagree there. The vast majority of computers in the world are either business desktops/laptops or home desktops/laptops. These don't need decent graphics built in. A very tiny amount have discrete graphics cards, i.e. only gaming and high end workstations.
Where did I say discrete graphics, business will benefit MORE from intergrated graphics than home users.
AS I said most home users need half, if that, of the power they buy. People want high def video's and crap games to run well and adverts tell them product X or Y will give them an unmatched hi def experience, they'll upgrade eventually even though in a lot of situations there won't be any real gain, heck half the time the performance improvement people feel(who generally do smeg all with their computers) is just from a non 3 year old install of windows.
Intergrated GPU's are becoming VERY good, and gpu accelerated software that up till recently has always been done exclusively on the CPU is taking off pretty big time.
Business users, presentations in high def, running various adobe products, video encoding(Intel and quicksync offers magnitudes faster performance and plenty of businesses could benefit).
As for finfet, essentially that is what Intel have done, they've just called it 3d rather than finfet. AMD apparently made finfet chips a couple years back(new process stuff is often tested literally years before retail products hit, and usually new processes start as sram chips as they are very basic in general).
I guess Intel are just playing on the whole "3d" craze going around at the moment though, I mean you can see from the picture, the transistor(most of it) hasn't gone 3d and they aren't being stacked so calling it 3D is mostly BS.
Anyway back to the whole APU thing, in general being seen as fast in one area is just a good thing, full stop, it doesn't matter if its desktop/laptop and non business. AMD have a shedload of market gain available to them if they have competitive products in every area as they are miles behind everywhere.
You're forgetting the main point though, Intel themselves are pushing towards APU's, marketing APU's and showing what overall system performance their APU's can provide. Also don't forget, the single biggest increase in performance from their old chips to Sandybridge, was quicksync, which is done on the GPU and is strictly an APU feature. So thats Intel who put billions in R&D and massive effort into their APU.
Intel are going APU in every single market, as are AMD, in which case yeah, pretty sure APU performance will be the most important thing.
