Well apple doesnt get a choice unless it wants to buy a licence for nVidia or change to the AMD 'Dragon' platform or to the AMD 'Fusion' platform when its released.
Well, that was my point. Apple's line up used to be
13" good CPU + good integrated graphics
13" good CPU + good integrated graphics
15" good CPU + good integrated graphics
15" good CPU + good integrated graphics + good discrete graphics
15" good CPU + good integrated graphics + good discrete graphics
17" good CPU + good integrated graphics + good discrete graphics
Good CPU + good integrated graphics is no longer an option for anyone in the Intel world, so now Apple must choose between
13" good CPU + bad integrated graphics
13" good CPU + bad integrated graphics
15" good CPU + bad integrated graphics
15" good CPU + bad integrated graphics + good discrete graphics
15" good CPU + bad integrated graphics + good discrete graphics
17" good CPU + bad integrated graphics + good discrete graphics
Or
13" bad (old) CPU + good integrated graphics
13" bad (old) CPU + good integrated graphics
15" bad (old) CPU + good integrated graphics
15" good CPU + bad integrated graphics + good discrete graphics
15" good CPU + bad integrated graphics + good discrete graphics
17" good CPU + bad integrated graphics + good discrete graphics
Or
13" good CPU + bad integrated graphics + good discrete graphics
13" good CPU + bad integrated graphics + good discrete graphics
15" good CPU + bad integrated graphics + good discrete graphics
15" good CPU + bad integrated graphics + good discrete graphics
15" good CPU + bad integrated graphics + good discrete graphics
17" good CPU + bad integrated graphics + good discrete graphics
with a much lower price spread between the different models.
