Well, those are not software quality issues. Some of those are design decisions, and have been with us forever, not random accidents: "Cut", for example, has never been on the Mac. Transparency in 10.11 is so lightweight you don't even notice it -- nothing Vista-like about it.
As for "total disregard of Fitt's law" that's not some decline either, as it's not worse or better than it has ever been in OS X.

Well, that qualifies as buggy software. But I have to wonder.
I've had an iBook, 2 MacBookPros (1 company issued), an iMac, a MacBook Pro Retina (current), 2 iPads and 2 iPhones thus far. And I've travelled all over the US, Europe and in several parts of Asia. I've never had any trouble with wifi, even to non-chain, el-cheapo motels.
The only offender has been my iPhone(s), which indeed I've not been able to connect to 3-4 places (restaurants etc) while traveling, over many hundreds of locations over 8 years. And I can't even know if it was because of the iPhone crapping out, or they using some crappy, third party router.
So I wonder, what are all those wi-fi issues people mention in forums etc.
