@ takemehomegrandma,

Your perspective is fueled by your desire to see a change in ISAs.
Since we haven't received Powerbook or G5 Mac support, there is still plenty of room for expansion.
I'll license either model (maybe both).
We don't need to consider an ISA change for at least a couple years.
And who knows what will happen during that period.

With IBM and Frescale's continued focus on further development of Power architecture, my vote is that we stay where we are.
Like X86 needs yet another alternative OS.
