the current generation of n2k:

- does not support 10/100, only 1000
- has serious etherchannel limitations
- no netflow
- no rspan / erspan

It's an interesting switch which should improve lots in the next generation
of hardware.  But right now, it is very specifically aimed at a particular
niche.  For that niche, it will perform very well indeed, but it's not
really a general purpose access switch.

wrt NX-OS vs. IOS, they are two different systems.  NX-OS is very young in
its development cycle; IOS is much more mature and has many more features.
