I agree that USB has problems. I do not think that FW was ever present
on all laptops and another interface for audio doesn't need to be
available on all laptops either, it just needs to be widespread enough
and stick around for a while. I'm not sure what this could be. Are all
the card interfaces vanishing as well? In theory anything with DMA
should cut it, right?
I see my fair share of laptops and ethernet is somewhat declining.
There are only few laptops without an interface, macbook air and some
versions of macbook pro come to mind. I guess apple has two reasons for
that: 1) increased use of wifi over ethernet 2) selling overpriced
adapters to people who want to use ethernet. What I see increasingly
more often are 'flat' ethernet ports. With those things you can't just
plug the cable in, you have to expand it first. This allows
manufacturers to build slightly slimmer laptops but I think those ports
will likely break much sooner than conventional ports. I guess this is
a tradeoff manufacturers are willing to make since wifi is so prevalent
nowadays. It is also an indication that ethernet is less important
nowadays and may vanish from laptops in the next couple of years.

Maybe thunderbolt will replace firewire, we'll see.
