This new MacBook announcement was just item after item of taking things to the next logical step, and it's setting a new bar which every other laptop manufacturer out there will now have to meet.

Apple did not invent the 'sub-notebook' form factor. There have been many notebooks without optical drives before it.
But more to the point, a netbook was optical-drive-free because you weren't expected to use it for more than just web browsing; you weren't going to need to load software onto it. The MBA was optical-drive free in spite of it being intended to be a fully-functional notebook computer. You would install software onto it over wi-fi. And you wouldn't need to rip CDs because you would buy all your music from the iTunes store. In 2008 that was still a bold idea.
Of course, one could argue they were specialist laptops which never had a large market. But maybe the same could be said of the MBA?
Apple's abandoning of the optical drive played a huge role in ensuring everyone provided a non optical disk way of getting their software or media content.
Where they were first (to the best of my knowledge), and were a bit controversial, was removing them as an option for their Desktops. That raised a few eyebrows.
Strictly speaking, Apple has not dropped optical drives across the line; you can actually still buy a 13" non-retina Macbook with one. Though given that it's worse in practically every way than the Air, and more expensive, I doubt that anyone does.
Do you mean they were the first to bring out a desktop/laptop with usb?
