You really can get an ASR9000 at a much better, similarly-
spec'ed 7600. Just spend some time with your account team 
:-).

This is a general problem with IOS XR-based systems. Even 
service-impacting SMU's that reload fabrics or line cards 
can make software upgrades a very annoying experience.

I've discussed this with our SE many times. He says Cisco 
are looking at optimizing the process so code updates run 
faster. I suppose time will tell, but as of now, we easily 
can spend 2hrs on a box if we're catching up with all SMU's. 
More if we're also moving up a release.

Cheers,

Mark.
