We were close to getting some for our network, but were unable to get any 
hard facts about people who are using them as "backbone" or "border" 
routers. In the end, we've decided to go with Cisco GSR's.

The flaws we tended to find were with not enough enough memory to hold 
full routing tables, or a limit on the number of route entries. Another 
flaw was mentioned with regard to the route caching - something about 
needing to hold in table of which IP addresses were on which port (usual 
switch behaviour).
