Existing M7i/M10i boxes are pretty darn old, and IMHO are getting very
close to the end of their useful lifespans. Even with the new CFEB-E
boards (which bring I-chip capabilities and put the old ABC-chip design
out to pasture), RE-400 or even an upgraded RE-850 are not exactly
modern or stellar performers on the control-plane, especially given the
rate that JUNOS is bloating itself. For about the same price as a
redundant M10i with 4xGE you could wait and get an MX80 with 4x10GE and
48x10/100/1000, and have a throughly modern platform which is FAR more
likely to still be useable in 2-5 years from now. Unless you're putting 
this up against a $4k ebay special, you should really be far better off 
buying an MX80 when they come out.
