The only things I don't like as much about the MX is the various flavors of DPCs they offer depending on what your application might be (queueing options), having to keep track of limitations on certain cards (like Cisco), and licensing of certain features. We've been testing the MX960 and have them deployed in a few sites today, and they are as solid as the M/T series. We've tested pretty much everything you've listed there with the box in both a core/agg role and found no real flaws that weren't software related, meaning they affected the M/T as well.

It's a great platform. It still doesn't compete with the 7600 on price for most of the market, considering there are tons of people out there that don't need the more expensive ESxx 7600 cards, but for those that are looking at 7600 w/ES20/ES40 vs. MX series, I'd take the MX.

We've been using Juniper M/T series in service provider scenarios for
a couple of years now, and really like them.  As part of an equipment
life cycle refresh, we're considering replacing our core (campus
enterprise) network with something in the MX series; a la this post:

We are very "glass is half empty" on our evals; while it seems most
are pretty happy with the MX boxen, I'm trying to find something
show-stopper that would make us go with another product.  We're
wanting basically a campus Ethernet version of an M/T box and all that
that implies (besides just shoveling packets at a non-blocking line
rate, we'd like full MPLS and RSVP/TE support, L2/L3 VPN, multicast,
IPv6, lawful intercept, etc), so I'm curious if anyone's demo'ed an MX
box as a campus core router and tested everything but the kitchen sink
and found something that Juniper says "works great", but in actual
practice just isn't quite there yet.

Basically, can someone give me reasons apart from "we don't need SONET
or any other WAN interfaces, and it's cheaper per port", why should we
NOT choose an MX box?  Are there any gotchas waiting in the wings for
someone who's used to the full flavored goodness that is the M/T
series?
