Unless ARM designs desktop and laptop level CPUs that can meet or beat the current X86 offerings, then ARM will not be a part of Apple's desktop/laptop market and that article is a lie. Metro is not bad at all, it's just not too good for a desktop or laptop. It's great for smart phones and tablets. The Medfield Atoms have great GPUs (the dual core one is supposed to have more or less equal performance to the A5X chip and have better CPU performance than the A5X), although the first few might not be record breakers.
Apple can't sue Intel for making a thinner laptop. If Apple really thought that they could do something, then they would have done it BEFORE the ultrabooks started selling.
Apple didn't go AMD because AMD had slower CPUs and had far too low volume production for the CPUs and APUs. Apple is also very focused on battery life, so Intel has been the obvious choice for some time. Until AMD steps up (steamroller might do very well if Trinity and Piledriver make a good enough jump over Llano and Bulldozer) with production and quality, they will not be chosen by Apple.
None of those articles really "fortified" your point, but they did show that you can try to use incorrect evidence in order to convince someone of something wrong just because that is how you want something to be seen as. That Apple thought about going with AMD, BUT DECLINED because of AMD not doing nearly well enough shows that AMD was not an option for Apple and is thus irrelevant to their plans until AMD can compete with Intel in performance, efficiency, and volume.
Cortex A15 I don't know about as I've yet to work with those. Cortex A9 is horrible at this though, branch prediction and instruction rescheduling is a very complex and power hungry piece of hardware to have around. Its like it's own miniature processor in and of itself. In order to keep power requirements down the A9 used an incredibly underpowered branch prediction / rescheduling unit, it might as well not even be there. That and the ARM ISA isn't very conducive to out of order operations. They used conditionally executed instructions as a way to compensate for this. It really is a perfect ISA for small lightweight processing as it gets the job done without needing excess hardware, the downside is that it can't scale to meet large complicated workloads.
Unless ARM can do something about their problems with scaling performance up to desktop levels, they will NEVER be more than an afterthought for Apple's Macs and Macbooks. They also won't be making it into any PCs, except for maybe the most low end PCs that replace the Atom based PCs if Intel doesn't make a desktop/netbook/notebook Atom refresh.
