The last Apple computer Woz had a direct hand in designing was either the Apple II or the II+ (I can't quite figure out which), over three decades ago. Woz was a genius when it came to minimal and effective designs and it's certain that he played a key role in getting Apple off the ground, but he has had no real impact on the company or anything the company does for nearly as long as I've been alive.
Woz helped build Apple into a successful company, but the scale isn't even remotely the same. The Apple that Jobs subsequently built decades later now sells more hardware in a month (or so) than Woz's Apple sold during his entire tenure.
