This isn't quite right.  The 7301 does offer a redundant power supply
option, but it's kind of lame.  It is not modular (you must order a 7301 in
a redundant configuration) and uses a special connector that forms a "Y"
cable to go to two different outlets.  The modular redundant power supplies
on the 7200 are much nicer.  It's also worth noting that the 7301 power
connector is on the same side of the box as all the interfaces, which is
kind of annoying.

The 7301 is essentially a fixed NPE-G1 in a 1U box.  It will have identical
performance characteristics to a 7206VXR with an NPE-G1.  A 7206 with an
NPE-400 will be slower; with an NPE-G2 it would be faster.

This is certainly true, given that the 7206 has 6 slots plus a modular NPE
and I/O controller.

This really describes the CPU performance rather than the backplane, and you
must take the numbers with the appropriate amount of salt, but at least it's
a rough guideline.

That is likely to be highly dependent on what features you configure and the
traffic mix.
