you've provided nothing but your opinion...I've tried providing data, benches, and common sense.
Not superior experience, in any way. AT BEST will be on par. The benchmarks you linked to' us were from the desktop version. The mobile, considering Apple restrictions due to thermal design, will be lower clocked, Turbo Boost or not, and that will provide lower performance.
So your beloved MBP 13" will have lower graphic performances than a 2 yrs old integrated chipset (9400M).
I definitely hope Apple will go for a discrete solution even for 13" MBP
The initial Core i7 laptops were power hungry beats of machines intended for gaming. Not only is there an emphasis on efficiency with Arrandale, but if I'm not mistaken there is also the change from the original 45nm to 32nm die, which should cut power consumption significantly.
Correct.
The i5 540M has a similar TDP of a C2D 2.66/2.8 Ghz, with a generic 10-20% improvement in performance, that is fine.
The ONLY problem here is with the integrated iGpu.
