Perhaps ARM will be used as co-processor of sorts. For example in an iOS mode where you don't want to completely boot to OS X. That could be interesting. If Apple were to go all ARM I don't think it would be an island. They could use Intel for the Mac Pro, and MacBook Pro. While the Air, Mini and iMac get the ARM treatment. There's also rumors of a Windows ARM version so that could help with users that still "need" Windows.
