Jamboard aside, I've really hesitated buying any Google product because it could be bricked any day, including Nest devices. Understand the business logic behind it, but sooner than later this is going to catch up to them.
I used to work in advertising, and it's remarkable how clueless and out the industry is about consumer feedback on this. There's constant back patting without realizing the actual ire shoppers have after spending $2k on a TV and still being sold as a product.
