Some of these I get, but I don't get the T9 thing. T9 was so bad! It took ages to type many words. Today's predictive keyboards are miles better.

Also, no software updates? Sure, every now and then there's a shitty update, but most updates are great. New features and especially bug fixes are amazing. Used to be that if something had a bug, you just had to deal with it. There's no guarantees it'll be fixed today, but many companies do fix their bugs at least eventually. The ability to iteratively develop is huge for software quality. These days, unless you're developing something that absolutely cannot fail (like a mars prober or radiation therapy machine), it's widely agreed upon that iterative design is superior to "waterfall" design of trying to plan it out all ahead of time. Part of why is so you can get feedback continuously instead of only after you've committed to months of tech debt.
