I'm not angry at Apple with regards to their desktop OS (I am a bit annoyed at how locked down their iOS devices are, but I switched to Android).
However I am *wary* of the future of OS X, specifically the fact that the late Steve Jobs was always talking about the "post desktop era" and that much like Microsoft they seem to be trying hard to move everyone over to tablets. So I've been catching up with Linux as a contingency for if/when Apple turn around and say "the Mac only accounts for 2% of our sales, so we're withdrawing them from sale". It could be 5, 10 years from now but the whole industry seems to be predicting the death of the desktop in favour of tablets and I'm pretty certain I'm going to end up one of those stubborn old fools who likes his 30" monitor, physical keyboard and mouse and the freedom to customise my own hardware. By then Linux may be the only desktop OS left, and us old-farts-to-be have to be prepared.
The problem it has at the moment is that developers and users alike have kind of invested quite heavily into the GNOME/GTK environment, only for GNOME3 and Unity to get "Tabletification Disease" and end up dumbed down and buggy. I feel that they were right to update the ageing GNOME2 and I don't personally believe that MATE is the answer in the long term, but that they jumped the shark in the process.
It's actually gone kind of backwards from when I was properly into Linux about 5 years before, when GNOME2 wasn't so old and.. 2D. Everything was solid, stable, mature. Now it's like the Linux Desktop, at least on the G side, has gone back to square 1. Basic features are missing and it's just not right in 2013 that the desktop should show graphical glitches and/or lock up on popular AMD cards for example, nor that I should have to do command line incantations to repair my wireless driver after an update, both of which are examples of my recent experiences with it. I'm capable of fixing things but do that for a living and have better things to do with my time at home.
On the positive side, I tried KDE and gosh.... relative sanity! They actually dare to give us controls and buttons and not treat us all like retards who will flip out if there's more than one button on the screen. But most of the decent software (IMHO) is GTK/GNOME based because we all had faith in Ubuntu (and look where that's led us - nowadays with Canonical doing their own thing with everything it's one step away from closed source). *sigh*
It's just..... a mess.
Getting a new camera (Panasonic LX7) and finding that Corel haven't added RAW support for it to Aftershot Pro and "goodness knows if/when they will", then going to my Macbook and having it work instantly on Aperture, was the turning point for me when I thought "why am I back to wasting my time messing with Linux again?". (Plus Aperture is so much nicer to use, but I was willing to make a sacrifice if Aftershot would actually work). I'm now severely tempted to about-turn and flow my way right back to OS X on the desktop and consign Linux back to a secondary drive for playing with occasionally and seeing if it ever matures. Life's too short, you know?
