Right, but my question is (cost aside) what's the advantage of an
atom+ion over e.g. an i3-2100 system?  They'll both have about the
same power consumption at idle, but the latter gives you a lot more
flexibility in terms of having a powerful general-purpose CPU,
rather than a weak CPU and an application-specific GPU.

And with the ion, you're messing with the proprietary nvidia drivers
(which, to their credit, are generally pretty painless to install)
and additional setup/configuration steps for making vdpau work.
