I don't know, as much as Google are able to come up with innovative products, those products (the physical ones) rarely ever affect our daily lives because they rarely are worth buying, or even possible to buy.
How many people do you know personally who own (or plan to own soon) a Chromebook Pixel? A Nexus Q? A Google TV? Google Fiber? How many plan to buy Google Glass at launch?
Now how many people do you know who use recent Apple products daily? Who buy new ones at launch?
Google mostly make niche products that aren't necessarily bad, but still niche products for a reason or another. Most of their income comes from services, mostly targeted ads with information mined from services like web search, maps, gmail, youtube etc. which haven't significantly evolved recently.
