I guess that a majority of customers who hate Yosemite hate it due to perceived bugs, not looks. App Store design makes it unnecessarily difficult to make good use of customer reviews. I'll revisit this maybe a few hours from now.
Based on the "functional" changes of iTunes 12 and 11 (e.g. killed the true side-bar that made it easy to do everything from one view in 12; you still can't resize icons in "movies" view and you still don't have cover-flow for that mode so the mode is ugly as crap or has no artwork in list mode without making the list "fat"); in 11 to further the "borderless look" they removed the easy-to-read speaker button that would tell you which speakers are in use for a hidden behind the icon in the upper left side that has no room to tell you which speakers are in use. EVERYTHING they do is to promote a "minimalist LOOK" but it's just a LOOK. You lose all this power without the full interface and whereas before they just hid the power modes, now they're starting to just flat out remove features in favor of even less buttons and dialogues. The "get info" button is now compromised as well. Things should be better not just
different.
I can only imagine the functional change horrors of Yosemite. I refuse to install it when I see no serious improvements offhand to OS X that aren't simply to cater to the iPhone crowd. Frankly, if it weren't for improved monitor support, I would have preferred Mountain Lion to Mavericks.
I can't speak for Harshan, but I certainly lose some ability to write rationally when describing something that was so hideous, it made me yelp.
Jobs may have respected Jony's abilities to design hardware, but making a nice looking CASE and making a nice looking GUI interface are two different things entirely. I can't put
all the blame on Jony, though. Apple in the '80s and '90s were notorious for making dumbed-down interfaces with no power features and no real multitasking for the masses. It's why I HATED Apple back then. I used an Amiga 500 in the late '80s and an Amiga 3000 throughout most of the '90s. I reluctantly bought a PC in 1999 and went through Win98 and later WinXP. I bought a Mac in 2005 and built a gaming PC in 2006 and haven't bought a PC since but have gotten two more Macs and one Hackintosh netbook since then along with three Apple TVs and two iPod Touches. The reason is OS X!
OS X did the impossible for Apple. It made the Mac a respectable powerful computer with real multitasking and even more impressive, it tamed UNIX (something I once thought impossible) and even made it a pleasure to use! Two decades since I first tried Linux and I still can't stand it. Yes, it looks polished on the surface now, but it doesn't take long before you realize you're either extremely dependent on repositories to get software in a reasonable time-frame for your particular Linux "flavor" or you're right back to 1995 building your own software yourself with compilers and making a mess that gets screwed over sooner or later when it's time to update the kernel (either let their updater screw it up or pray that it doesn't or start compiling yourself. I had several builds screw up several updates so I'm not exaggerating when I say "their" updates don't work. You always end up installing from scratch and losing all your application configurations, etc. in the process. At best, you can keep your documents. It reminds me of Windows come to think of it....
Apple has actually done a respectable job of making it simple to update the OS and even move configurations over from machine to machine. It even moved my PPC machine over to the Mac Mini without much difficulty (only a few PPC only apps failed by that point). Even more impressive, you can easily boot from an external drive as if it were the internal one and thus make fully functional backups that make it a breeze to do things like change internal drives (even on Macbooks) and go back to older versions if they really screw something up royally. It's a nightmare in Windows to make true backups that "just work" on a reboot. I've used several packages and it's downright scary when it comes time to test them with a real problem.
But Apple is taking a nice functional OS that could use some real improvements (even better multi-monitor support, various bugs that need fixed they keep ignoring like no movable side-bar dock) and better gaming support in both drivers and OpenGL updates and hardware (Apple has had GPUs behind the curve for the past decade; they seem gung-ho to improve iOS graphics but don't seem to give a crap about the Mac unless it's to drive a bigger monitor) and now they're trying to CHANGE it based on a few review sites that keep talking about OS X like it's ancient and horrible to use. It needs this "fashion makeover" by the way I read it. You don't mess with perfection. You don't put bumper stickers on a Ferrari. But to me, that is exactly what Apple has been doing.
I believe it's the iPhone sites more than anything that drive this "urgency to change for change's sake". Oh the iPhone still looks like it did when it first came out except for these improvements. That's SOOOO 2007!
SOOOO WHAT? You use what works. But once they changed iOS, you just knew that they would feel the need to change OS X so they "matched". Unfortunately, what works for a small 4-6" touch-screen device (and I'm not sure FLAT works great there either) doesn't necessarily work for workstation and desktop class devices with 28" and larger screens. Depth helps in such environments. I could have lived with Mavericks, but no they keep taking it further and further down the 2D 8-color road until I think I'm in 1994 again with Windows 3.1 or OS7.
