Right circumstances = almost always. Actually Linux makes sure that it's

That's not supported on all systems. An Indy for example is limited to
128mb RAM as shipped by SGI (256 with aftermarket parts). There is no
point in supporting 64-bit address space on such a system and so SGI doesn't
support only N32.

External drives work just fine and can be hidden where their sound isn't so

Yep and they co-exist nicely.
