If you don't like it, go back to thick and low-resolution PCs then. I certainly wouldn't want to, not after having actually used a 5K display.
No!

Apple's strength is their software and hardware combo ecosystem. If you're dismissing all of their software you might as well not buy an Apple product because you are paying extra for the stuff you don't seem to like. You're also buying the thinnest and lightest hardware that include Yosemite which you also hate.
So what do you like and why do you buy any thing from Apple?
That's almost true. I buy things from Apple because since 2005 that's all I bought. The hardware still is the best. My major gripe is the software-- the iOS-ification of their desktop apps in particular.
My 2012 15" rMBP is the best computer I've ever owned. It will be out of warranty next month and I'll run it into the ground. I may not like some hardware decisions they have made over the years, like getting rid of the pulsing light on my old MBP, or ditching the magsafe, or getting rid of the Apple Logo backlight, etc. but they still make the best hardware. I don't have to agree with everything Apple does to like their stuff.
Their software is definitely their weakest link.
