Apple Another Apple-to-switch-Macs-to-ARM post. "Apple engineers have grown confident that the chip designs used for its mobile devices will one day be powerful enough to run its desktops and laptops, said three people with knowledge of the work, who asked to remain anonymous because the plans are confidential. Apple began using Intel chips for Macs in 2005." No idea when Apple will make the switch, but they will do it. I'm thinking 5-10 year timeframe.

I think they can run iOS apps on a Mac right now if they made an emulator, like they could run PPC software on Intel machines.

...but you already have a iOS device emulator for Mac OS X... for 5 years now.

they (Apple) do not even call it "emulator" but rather "simulator" (since there is nothing to emulate! e.g. ARM ;) )

so this is not a issue (or purpose)! - switch Mac to ARM and than run iOS apps on Mac.
you can do it today.

--- but

take a look on today Mac OS X; you can burn CPU 100% if you do:
1) rendering
2) zip/unzip stuff
3) run Adobe Flash ;)
4) some heavy PhotoShop-ing
5) Aperture
6) complex javascript/html pages

... and all this stuff could run even faster on GPU! (e.g. new Aperture heavy relies on GPU!)

on other hand, for:
1) chatting
2) skyping
3) typing
4) exceling ;)
5) emailing
6) ~browsing

you do not need nothing faster than todays ARM!

all professional (content creation) application could benefit more from GPU than from CPU in future (as we have more and more advanced underlying infrastructure: compilers, languages, frameworks...)
...and one very important thing for future: it is easier to double GPU power than CPU power!
