Intel have spent over $28 BILLION in 3 years for R&D, so apples 1 billion does not seem to bad, but of course it depends on what extent they modified the original ARM chip

Apples and Oranges. Intel owns at least 8 fabs, each of which costs $1-$2 billion to build/update each time they switch to a new process generation. Intel also makes many more variations of chip designs (Itanium, i3,i5,i7, graphics, chipsets, etc) than does Apple.
