Good point. You can actually do rolling upgrades with RAC under if you know how. It will just become easier with 10g.

This might be related to geography. I would expect that there would be more need for larger boxes in the US than in Alberta or most places in Australia. I see a very large percentage of boxes at >2 CPUs.

That goes without saying. No doubt there is some salesperson somewhere saying there is no relationship between Exp and DataPump.
