What ever about the fine detail...
ARM is looking viable.
So why doesn't Intel have its cake AND eat it?
Intel has their own foundry
Intel has some of the best production, marketing and process engineering
Intel has an ARM licence, and certainly after the ARM chip sale to Marvell kept one or two Comms SoC.
So why isn't Intel making an SoC with four ARM cores, massive L1 cache, all the I/O (disk I/O) & memory interfaces... Just add RAM, ethernet magnetics and power?
It's not an either or. With MS promotion of ARM, likely Apple move to ARM for Mac Air and later all Macs and Intel promotion of Linux what is their problem?
