Do these types of threads appear after every update Apple makes?
Typically, yes. And it stems from how Apple handles updates.
Just about every other PC vendor have price decreases (or incremental hardware updates) every month or so. So if you buy a, let's say, Dell XPS when it first comes out, it's $1500. If you buy that same model 6 months later, it's $1300. If an update comes out that day, it's $1500. So no matter when you bought it, you either pay full price to enjoy for the full six months, or less money to enjoy for fewer months.
Apple charges full price up until the day of the update. If you buy right after a particular model comes out, you're golden. If you wait 3 months to check out user reviews, you still pay full price. If you wait until the day before an update, you still pay full price.
So the frustration is mostly due to how Apple handles updates and pricing.
