Well it seems IBM has decided to give the AS/400 a new name. It is now called "PURE SYSTEMS" and seems to be identified as a "pureSystems" mark.
Previously the technically were called POWER SYSTEMS, (I think?) and that identifier was just barely starting to be picked up "POWER System model 720 with IBM i" was a mouth-full but no more that "MAC BOOK PRO with Mountain Lion".
I wonder if the folks in Michigan have issues with IBM plagiarizing their slogan? Visit pureMichigan.org for more information.
