The yellow Google Search Appliance for enterprises is about a decade old. You can still buy them today.

The Nexus One was branded Google. I wouldn't say it's supported by Google anymore because it doesn't receive firmware updates. Google first released it in early 2010.

The Chromebook CR-48 was first released in December 2010, but it wasn't a Google product (unbranded). It still receives software updates today.

BTW the new router isn't a Google product. TP-Link makes it. Google just controls the software, the way Microsoft updates Windows on third-party PCs.
