When my MX80's and ASR9001's run out of steam (we use these for peering
and transit), I'll look at the MX104, ASR1006 and ASR9904 as potential
replacements.

I think the MX104 is good enough for peering/transit. I also think it's
good enough for low-speed edge routing, e.g., non-Ethernet.

I'd likely never deploy an MX104 in places where the MX480/960 or the
larger ASR9900 routers are better-suited, i.e., major Ethernet aggregation.
