Welcome to 1998 :) http://en.wikipedia.org/wiki/File:Apple_USB_Keyboard_B.jpg
Back then Macintoshes were advertised as "keyboard not included" so Apple got to soak you for a very well-engineered item.
Perhaps: M0115 vs. M0116 is probably the quintessential AT vs. compact layout conflict, though, so I'm sure there were plenty of supporters on either side. I also assume that the compact M0116 actually sold significantly more, as I've almost never seen an extended keyboard used with a non-modular Mac like the SE or Classic. The M0115 was consciously part of the Macintosh II revolution (or counter-revolution?): SJ was famously among the people who presumably preferred the M0116 http://www.flickr.com/photos/jurvetson/841771 .
