The RS6000 / P Series / System P / AIX platform is much bigger than the old AS400 / i platform these days.
Although the hardware is now common and just referred to as Power the number of AIX "instances" versus "i" is HUGE, not only are there still millions of standalone and older AIX systems out there, the take up of new AIX instances is enormous and still increasing compared to i which is sadly maintaining a steady decline.
As an IBM i person you should be aware of the whole i development and support structure steadily receding back to Rochester as the product footprint recedes.
Some have been saying, for years, that i is so stable that little development is needed and the same applies to the support structure but they are obviously kidding them selves.
IBM will continue to maintain the i environment for the foreseeable future but the writing has been on the wall for a long time, where as AIX is now the leading enterprise unix and continues to go from strength to strength - and I'm not just posting this because of my involvement and love of AIX i have very real and direct experience in a wide market of the growth of AIX and the decline of i.
HTH.
