Right now I'm using a mid-2012 MacBook Pro that I've just upgraded with a Samsung SSD. The reason I chose to upgrade the storage instead of buying a new MacBook Pro was that I couldn't justify spending $3000+ for a laptop that was unrepairable and unexpandable, and would have to be sent to the recycle bin if it broke after the AppleCare warranty expired. I'm hoping this upgrade will get me through the next couple of years, but what happens after that?
At some point I will need to buy a new laptop. So what are my choices, if not another MacBook? A Windows 10 machine? Absolutely no way in hell. Put Linux on a PC laptop? Maybe, but avoiding the time and effort of supporting a Linux installation is the entire reason I use a Mac.
But what if (for example) Google decided to take a page from Apple's playbook? What if Google were to develop its own laptop with a real Linux / UNIX / BSD OS with a nice GUI, and support it the way Apple does? Not just a Chromebook, but a laptop with a new OS to complete with MacOS? And what if that laptop had a sane upgradeable / repairable premium design, without Apple's obsession for thinness and appearance over functionality?
If such a laptop existed, I would buy it in a heartbeat. And when I did, I would almost certainly switch from an iPhone to a Pixel, and from the Apple to the Google ecosystem. Everyone says "Google is the new Apple", so why shouldn't that be true? Google has the culture and the resources to play the game by Apple's rules, and take a huge chunk of mindshare away from Apple. Not to mention the fact that Google apps like Assistant and Maps already leave Siri and Apple Maps in the dust.
There needs to be a new option for laptop and desktop machines. Apple and Microsoft have both gone off the deep end, pursuing development paths that are leaving power users in the cold. Google could step in and become the new king of the mountain in very short order - if it has the will to do so.
