No mention of the iPad or OS X.
* the first genuinely usable, affordable GUI (i.e. the Mac)
* the iPod
* the iPhone
I'd say the Apple ][ is debatably on that list (the first personal computer than "just worked" or something). NeXTStep is a wonderful OS with a lot of Good Stuff in it but it's a piece of a product. The iPod Touch and iPhone are fairly obvious evolutions of the iPhone.The other missing item isn't an Apple product: Pixar.
To my mind, that is the product that really touched off the personal computer revolution. As you mention, the Mac paradigm shift was about the GUI, Mouse, and taking what they started with the I and ][ to the next, more refined and "product-ized" level.
