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.

More cores will allow each core to spend more time on a certain task, but they can't work together to do one task faster (I think).

So having a whole lot of ARM chips in your Mac doesn't make it faster at CPU intensive tasks than a Mac with 4 or 8 x86 based cores.

Then again, do they need to be? Are there so many tasks that require a lot of CPU to make it show?

When you move from a normal hard disk to solid state you'll notice what a bottleneck it was.

The CPU spends a lot of time being idle. So my guess would be that a computer with a solid state disk, enough and quicker memory, faster system bus can work very well even if it has ARM CPUs compared to a x86 machine.

Around here I have a PC with Athlon XP 1700+ (1.46 GHz, but actually set to 1.1 GHz for hardware conservation purposes), an 11 year old CPU.

And you know what? It's still quite fine for the typical stuff (browsing, office, IM, basic media consumption), the idle thread takes ~90% of CPU time.
Though the machine has, yes, a bit more RAM than was typical in its heyday - 768 MiB. If it was dual CPU and with an SSD, I guess it would be very comfortable.

Speaking of dual - on my dual Pentium II 266 the largest "consumer" of CPU power is also the idle thread...

I once heard a story about a programmer who had asked how to kill the idle thread, because it was taking up 99% CPU time(...).
