I thought with the arrival of MBP2018, the waiting hell were ended. Now that we discover so many problems with the MBP2018 across different configurations, I am still in this hell of spending full time checking current user's reviews, test results and wonder if I should look for other manufacturers.
Given that Apple has been producing machines with issues for 3+ years (we wasted over a year waiting for the redesign which lead to problems with keyboard of 2016, 2017 and perhaps also 2018 models and now thermal throttling).
Looks like the only way to break out of Apple's waiting hell is to stop using Apple computers.
It's a "hell" completely of your making. The new 2018 MBPs are excellent machines, and they've improved the KB with a silicone membrane. The KB is also covered for 4 YEARS. Every laptop throttles, and that should be a non-issue for you as this machine will be faster than your 2010 one by a ridiculously large margin. In the real world, 99% of people have no problems. You're spending way too much time on these forums and getting influenced by the rantings of a vocal few. If you're been running your business on an ancient 2010 MBP, then I find it hilarious you're so worried about throttling on such a faster machine, throttling that seems consistent with other processors and previous Macbooks. Youtubers have focused on it because every Apple release needs a "scandal" for clicks, and in the absence of anything else, people have pretended to make this into a thing.
But truly, you should probably seek some real help, since you've stated how "depressed" you are, how you spend entire days refreshing this website for updates, and how you've had "no productivity" for 2.5 years. That has absolutely nothing to do with Apple, and everything to do with your own decisions and mental health. Seems like you have some kind of irrational obsessiveness. Buy the new MBP, and be open-minded enough to adjust to the new KB. I did, and I haven't looked back. I can type faster with less effort. It will be such a massive improvement in every single respect, from performance, to weight, to screen, audio, etc. Or, buy something else. But stop the incessant whining and self-destruction, negativity and cynicism, it doesn't benefit you or anyone. And stop waiting for a magical product that may never exist. Somehow, everyone else in the world is getting by with whats available, and I'm sure you'll be more than fine for YEARS to come with the latest MBP since you've been chugging with your almost decade old model with apparently not enough incentive to upgrade. Something tells me you don't use your machine for anything intensive at all.
