Overall, Apple’s 2018 products are sloppy junk. Apple Watch Series 4 is the only piece of hardware released this year that isn’t sh*t compared to previous offerings.
I don't think the products released were "junk". I just think that Apple set themselves an extremely high and lofty expectation based on price points.
if you're going to charge 10-30% more than the market is already going for, than you need to offer something to differentiate that justifies that value.
the argument is that while the products are still top end (yes yes, with some known issues), they don't offer that mass product differentiation to justify such a higher price tag. And we all know the best way to get people riled up is to ask (or force) people to part with more of their money.
But if we look accross their product lineup of 2018, none of these products are bad. All have compromises.
HomePod: Fantastic quality audio with a fairly good integration with SIRI / Apple services. But compromises by being the only "Smart" home speaker Apple offers. at $350, it's trying to go head to head with premium sound, but is trying to sell featuresets that are available from the competition now as low as $30. if you're looking for a home automation tool first, the HomePod's price is going to be a massive barrier.
Watch4: This was as you said probably the best off the offerings as it actually HAS something that sets it above and beyond what anyone else is doing right now. EKG support. You can sort of justify the price point as if you want a watch that can do EKG, this is your only current option.
Mac Mini: The new Mini refresh was well needed and the current parts that are available are all top notch. they're great quality. the compromise however is thermals aren't great (and should be better). Again, there's nothing grossly wrong with the Mini and it makes a great headless Mac Computer... except that the price again gets in the way. You can get smaller, more powerful computers now for $400-$500, several hundred less than the Mac Mini. So this is again where pricing gets in the way of a great product.
iPad Pro: The new iPad pro is probably the nicest looking iPad they've made (IMHO). i love the straight edges of it. And again, it's one of the most powerful tablets available. it should be a run-away tablet success, if it weren't again, for the price. it's priced like similar 2-in-1's and priced near laptop (if not more) price points. Yet, due to software limitations isn't really a full fledged computerexperience. So again, the pricing gets in the way.
iPhone X(s)(+): Stellar phones. lets be honest there's little to complain about it. whether you like the notch or not is personal. the headphone jack argument is long over, we lost, so moving on i wont even ding the device for it. However, again, 999 price point. the iPhone might be quality wise one of the best built phones out there, But it comes with slightly smaller feature sets than most of it's competition. There's no massive product differentiation that justifies a $999 price tag. Especially considering that the competition are all coming in at a starting price far lower. Heck, the only device that starts at $999 is the Note 8 which is a hyper Niche product that is arguably the BEST overall phone (and has won numerous awards).
iPhone Xr: this one is the hot button topic. is it a "cheap" iPhone or is it a premium iPhone with some compromises to keep its price down? is the pricing at the old flagship price (pre X) justifiable in 2018 or is it reaching too far for something that's still using an old LCD? again, if this phone was 599 I don't think there'd be a debate. it would fly off shelves. but at $749? it's facing stiff competition against the likes of devices like the S9, P20, and other android flagships that are offering far higher overall "specs".
MacBook Air: Similar to the Mini. long awaited refresh to bring it up to current modern parts... yet also gets a price hike despite competition offering similar, if not stronger components for less. It's going up against the likes of device (such as the Razerblade stealth as an example) that are offering similar form factors, but already with high res displays, and 4-6 core U series CPU's instead of Apple's lower end Y series.
TLDR: Apple's 2018 products in a vacume are not bad products, minus a few technical issues that they must answer to. It's the pricing that has made the value proposition start to wear thin for many users. Those prices set extremely high expectations, which Apple isn't fully capable of delivering on. This is why we're startin to see a lot more "haters" who once were fanboys no longer able to justify what Apple is selling.
