The iPhone User’s Guide contains lots of interesting information about the iPhone. But the most interesting thing, to me, is that the document was created on a Mac using Adobe FrameMaker 6. This version of FrameMaker was released in 2000 and ran under Mac OS 8 and 9. FrameMaker 7.0, the last version that ran on Macs, was released in 2002. Old Mac OS software can run under Mac OS X in Classic, but only on PowerPC-based Macs, the last of which was discontinued almost a year ago. Apple is apparently using some old software and hardware to document its newest product. I totally understand; FrameMaker 6 is a great piece of software, and there’s nothing like it for Mac OS X.
