Like many people I have a drawer of batteries. Mine includes some oddballs like a box of CR2016 coin batteries. Coin batteries are famed for their long shelf lives (10 years or so), so finding they are best before June 2007 (tested them, all dead) tells me I need to sort out that drawer.

Bought my 2nd gen #Nest learning thermostat when they were released in the UK in May 2014. I knew #Google was ending support, and It stills operates my heating (breaking that in late October would've been a dick move) but have to work out which features are gone. Another #Google product killed.
