Woz was one of many people who designed microprocessor based computers in the 1970s (I recently started reading back issues of Dr. Dobb's Journal https://archive.org/details/dr_dobbs_journal_vol_01_201710, and the variety is astounding), and far from the first one, though he was very good at what he did.
What really set apart the Apple II from many of its peers is that it came preassembled, in a neatly designed case (though the Commodore PET and TRS-80 were pretty much released at the same time), and those esthetics were due more to Jobs than Wozniak.
Jobs did not write product code, or design boards, but he had a constant presence in the design of Apple's products and many (though by no means all) of his inputs changed the products for the better.
This is much more true than the parent comment, but nobody invented the concept of an integrated system in a case with keyboard and screen. That's because said concept is called a "video terminal" and had existed for at least a decade prior to the mid-70s. In fact one of the prime target markets for the first generation 8-bit CPUs was...video terminals. A late-70s personal computer is really just a video terminal that has been made programmable by the user. The hardware is pretty much identical.
