And I still can't resist linking to the My Consulting Experience blog for a discussion of how to create a Custom Key Flexfield (KFF) in Oracle Applications.
An op-ed piece from someone at the curiously named iHeavy, Inc +1-212-533-6828 blog who has tried both side of the Apple/Android fence: Why The Android Ecosystem is Broken.
