Ok.  IMO it's important for networking to work out of the box, so we
should avoid e1000 as default.
I don't think you can buy a new PC with a NIC supported out of the box
by Windows XP.

rtl8139 works out of the box.

That doesn't seem to bother the PC manufacturers...

I'm sure it bothers users.

The e1000 works very well in Windows XP, given that you install the
driver from Intel.  And e1000 is certainly more common and better
supported than ne2k in more *modern* OSes.

I fully agree with Anthony:
  "the average user is better served with an e1000 vs ne2k."

But this of course boils down to a discussion about who the average user
is.  Anyone having any statistics on that?

Anyway, most people will know that they may need driver disks when
installing ancient OSes on modern computers.  With QEMU they even have
the option to change the hardware with a flip of a command line.

The ne2k default is misleading.  A common assumption is that developers
know best, and that you need a good reason to change their defaults.
This may trick people into thinking that the ne2k is the best NIC choice
for QEMU. And I think everyone here agrees that it is not anymore.

The best choice for Windows XP is virtio, but we sure won't be making that the default. Given that e1000 gives 0 Mb/sec out of the box, I think it's clear that rtl8139 is better. If people are interested in performance, they can change the default and download a driver (e1000 or virtio).
