Launch
Apple introduced it on August 7, 2007 as part of the new aluminium and glass iMac line, per its official press release: the iMac shipped with this ultra-thin aluminium keyboard, 0.33 inches (8.4 mm) thin at its front edge, and two of the computer's five USB 2.0 ports sat on the keyboard itself. It replaced the Apple Pro Keyboard and its white A1048 successor in the line; per Wikipedia, it is model A1243.
Marketing
The press release described it as part of a "clutter-free" desktop, matching the new iMac's aluminium and glass. Wikipedia records a historical detail: it was Apple's first keyboard in 27 years to drop the Apple logo from the Command key, a legacy of Apple II days. It existed in two variants, MB110LL/A and MB110LL/B, the latter from July 2011 with the F3 and F4 legends updated to Mission Control and Launchpad, per Wikipedia.
Flaws and fixes
In March 2009, when the wired compact A1242 arrived, this model was renamed "Apple Keyboard with Numeric Keypad", per Wikipedia. It stayed in the catalogue for a decade: Wikipedia dates its discontinuation to June 5, 2017 and identifies it as the last wired keyboard Apple made; Magic Keyboards have been rechargeable ever since.
