I have been using Lenovo Tab M9 tablets for a couple of years. They generally work well, but eventually updated with a system application called Tips that started throwing notifications for Temu and some other garbage. The app can be stopped until the next reboot, but not removed (not that I have looked for any elaborate way to remove).
Also, every update brings a non-dismissable app installer notification, that will by default install about a dozen garbage apps every time unless you deselect each of the apps. Everyone involved with this needs to be fed to sharks. Again, the tablet itself is decent, but I paid for something that I do not own.
My family lived (1960s) inland from Los Angeles. On car trips to the beach, our eyes would start burning as we entered Los Angeles proper. We took a vacation trip to Hawaii. Amidst the excitement of my first jet flight (707), I noted a distinct brown band in the coastal clouds that we were climbing through.
Years later, in Vietnam turmoil and the rise of an ecology consciousness movement, and calls for "significant, meaningful, and relevant" education, my UCLA freshman chemistry professor (the late Dr. Mario Baur) announced that the day's lecture would be not from the syllabus, but instead on recent findings in smog science. He described photochemical mechanisms in smog formation.
Some years later, I worked in a Los Angeles highrise building that was not very careful about roof access. The air even at 24 stories, smelled nitric like Young Hall (UCLA Chemistry), plus a slug of ozone. Automotive rubber parts turned into glassy garbage after a couple of years: weatherstripping, wipers, radiator and vacuum hoses. Uh, what about my lungs?
