Yes, it is some nice stuff...

In particular, having the hardware partitioning capability plays nice
with Oracle licensing. Under KVM or Xen we still have to license the
entire system.  This probably won't change with the newer kvm, but one
can hope.

On the Linux side I would like to see how KSM (kernel memory merge)
stacks up against memory compression on the Power7 side. Not sure if
this made it into RHEL6, but hope springs eternal...

Storage management is always a big issue for me.  AIX has some really
great tools for managing disks. In Linux the LUN, block and fs layer
are still relatively decoupled which gives an enormous amount of
flexibility but certain types of changes require multiple commands on
Linux.

On the desktop side I've been running RHEL6 as my primary environment
since release. Transition was easy. My old kickstart files needed
tweaking, but so far it's been a breeze.
