For all you doom & gloomers - would you ever consider buying a WinTel machine? There's your answer right there.
I am a long time Apple user. Between my 1998 powerbook G3 and my 2011 macbook pro, I've owned 5 mac laptops, 4 mac minis, and 1 iMac. 2012 was the peak of Apple for hardware and OS X. It has been a shockingly fast descent into depravity since then.
I just did switch:
$370 for i7-4790k, MSI Z97 motherboard, and 16 gig of ram as a bundle a tiger direct
$255 for an MSI GTX 970 (black friday door crasher)
$120 for a 480 gig SSD
$90 for a 4 TB hard drive
$150 for a case and power supply.
Total cost, $985 for a machine that will destroy and Apple computer on the market in sheer performance.
And before you give me the usual story about OS X being so much better than Windows, that is the real reason I did it. Yosemite/El Crapitan is so crippled and such an ass-backward design, OS X is completely unusable. Windows 10 is an absolute pleasure next to the torture that is the current OS X. Between hiding the file system as much as possible in finder, even safari hides the url of the page you're on until you change that...they have ruined OS X.
As someone who has lived Mac for almost 20 years, all I can say is Windows is so much better than OS X, I only feel sorry for the people still stuck on OS X because of their outdated impressions.
There simply isn't all that much to improve. They can get longer battery life, faster SSDs, faster processors, etc., but a mobile phone has been perfected as a rectangular object with touch screen and a form of touch ID. Force/3D touch fails to impress me as true innovation. But it's probably as good as it gets. Similar to Adobe CC products or Office. At some point you really run out of stuff to stick into a word processor.
First, people have been saying for centuries there's not that much left to improve, and they've been wrong every time. Just because Apple isn't doing it and you can't picture anything outside Apple doesn't mean there's not plenty of room. Can Siri fully process natural language in any language and respond as smoothly as if you were talking to a real assistant?
Second, Apple has been making their products worse for years. You say you run out of stuff to stuck into a word processor. Apple is running out of features they can pull out of their word processor. Pages for OSX used to be fantastic. Now I use MS word because Pages is crippled down to act like a defective tablet program.
Year after year, apple takes away features, performance and functionally. But they sure do a great job making their useless crap thin.
Compare the feature list of the 2012 Macbook Pro to any laptop Apple makes now. 2 industry standard drive bays, 2 industry standard SODIMM slots. Ethernet. A magsafe cord that doesn't fall out if you breathe on the computer too hard. Glossy and matte screen options. A battery that's easily user-replacable. It's just sad what Apple users have lost in the past 3 years. And what have they gained? 0.25 inches thinner, a few ounces lighter, and a bag of extra accessories to make up for all the stuff that's no longer in the computer.
I think it is a combination of this, and that the markets are maturing so while Apple is still being just as innovative with new technology as they always have been the changes in technology that they have to work with are getting smaller and smaller.
Really? Try looking outside the Apple reality distortion field. The next few years are going to be amazing for computer users, and apple is going to be left choking on dust.
VR is going to disrupt everything. Facebook invested $2 billion for a reason. Apple facetime is going to look so quaint when you can video conference in VR. Or preview vacation sites, tour properties, and watch movies in immersive environments. 5k iMacs will be a sad joke when you have a wall full of virtual 8k panels. Just turn your head to render the part you need to view. Read a bit about where this is going in the next 5 years. Apple is already out of that club because they don't make a single machine powerful enough to run it. But hey, $3 billion on beats was a pretty good move too compared to $2 billion for oculus.
This is the amazing future we've been reading about for years, it is amazing what is available. And Apple still sells the same computers now as they did in 2008 only thinner and with more pixels (but not enough processing power to drive all those pixels).
