Well, iMacs, Macbook and Macbook Pro are best in their area, or does any PC have so incredible Touch ID? Multitouch pad? Aluminium design wise case? Retina display+macOS HiDpi handling? 5K screen? High performance SSD (better tech than the samsung EVO Pro)... etc
Ah! You mean Apple don’t update too often the macs? Yep that’s right, still, they are simply best designers computers with the best and most complete features (Mac Pro aside...)
sounds like you're about 10 years out of date...
iMacs, MacBooks and MacBook pros are far from "leading in their class" these days. Numerous hardware issues on the Pro laptops. Thermal limits on almost all their devices. Questionable Keyboards with reliability issues.
Other manufacturers have also started putting fingerprint sensors on laptops for a long time now. The ones for example on Lenovo laptops have been the equivelant style touchID tech for a while now and work just as smooth.
ALL laptops these days are using multi-touch glass trackpads.
Aluminium design case is just a preference and purely subjective. Especially since there are lighter and stronger materials being used by many of their competition, like Dell's Carbon fibre for example.
Retina Display is just marketing term for high DPI displays. And yes, you can get PC's with high resolution displays. Many standard. And many cheaper than Apple's offerings. "retina" is nothing but marketing sale numbers. Apple's 13" "retina" display is 227 PPI. Razer's 4k Display on their stealth is 331.
Windows has HiDPI scaling. the problem here isn't the OS, it's the legacy applications who refuse to update to use the API's for the scaling. Any windows store UWP program will handle high dpi scaling quite well. In fact, it can even switch between scaling on the fly (for example, my primary display is 2560x1080, my secondary display is 4k. I can drag a program between monitors and it will scale automatically to best fit that resolution.
5k displays are not unique to Apple and can be purchased, used separately. However, they're not immensely popular because they are a non-standard resolution not generally used in the consumer space. Nobody produces 5k content. There's no streaming / content delivery system that supports 5k content. Nobody is complaining that it's available, but it's also not the tremendous selling point outside of a few content producers.
They are also not the "most complete" with the "most features". there's enough evidence in this thread alone of ppeople talking about needing HDMI ports, SD card readers, etc. Pulling these out and saying "just buy a dongle" doesn't make the device "the most complete". especially when you literally have half of their computers who don't even have a function row anymore. There's nothing wrong with the touchbar, it just doesn't replace a function key row for those who actually need it.
the simple fact is that Apple is no longer making the best computers. they keep pushign for "thinner" computers, while sacrificing performance and build quality, while raising prices outside of their competition. a lot of what you said was true back in 2010-2015 before much of the competition caught on that there is a market for high end laptops, but in today's marketplace, Apple's primary differentiator that sells Mac's is MacOS. from a purely hardware perspective, Apple's computeres today are NOT class leading in most regards.
Don't get me wrong, they're sexy computers, with an incredible reputation and a culture surrounding them. But from 2015-2019, Apple's computer division has been woefully neglected and poorly designed.
