Search is impressive, and fast. I can type in beach 2014 and pictures from our family’s beach trip in 2014 come up nearly instantly. I haven’t tagged these photos explicitly; Google’s algorithms have inspected them, determined they are photos taken at a beach, and looked at the EXIF data to see they were taken in 2014. (To be fair, these photos do have a latitude and longitude.)
I’m still not thrilled about having all my photos stored on Google’s servers, but the service is just so darn good.
