While workstations for developers have bigger and completely different
requirements, in general the most demanding applications for ordinary
sixpack-joe are hd-video transcoding (which actually isn't memory
intensive), image manipulation (this year's basic $100 models already
sport a sensor of 14 megapixels => 45 MB per image layer), and
surprisingly web browsing.
The ARM equipment support this by providing powerful co-processors and
having a tiny (Thumb) instruction set. It's really hard to see where they
would need more than 4 GB of RAM.. even according to Moore's law it will
take at least 6 years for the top of the line products to use this much
memory.
but they work on 64bit:

Hmm I didn't know about that. I thought I read some months ago that
porting ARM to 64bit is almost impossible.
As a side note, a comment on the article:
"However, it's easy to imagine a service such as Amazon's EC2 offering
virtualized Linux instances without the user being aware that it's an
ARM setup, and these could be cheaper than equivalent x86 instances
(perhaps even making for a "budget EC2" service)."
This is BS, because the user is *directly* using EC2 VMs (can use his
own binaries etc), so he *will* care if it runs x86 or ARM. And I don't
think anyone would want to emulate x86 on ARM...
