At the first pc repair shop I ever worked at, I came into work a little too baked one day. Spent over an hour trying to find a hardware issue, then fumbled my screwdriver and dropped it on the live motherboard. One tiny spark, and that mb was done. Replacing it solved the original problem, so no harm no foul.

It doesn't take very much tech savvy to join the Windows Insider program, though. Especially when compared to trying to install custom firmware or the newest Android version on other phones.

Previous builds I had ALOT of issues. Apps crashing, features not working, even had my phone refuse to unlock one time. This build is surprisingly stable, and pretty good on battery consumption. Hell, they couldn't even get edge working in the last build, and I had to reset my phone to update it. Price you pay for using a pre-release operating system, though. I'd say it's pretty near finished at this point. (Well, as finished as any os that is.)

I know I'm gonna get downgraded real fast for this, but my $50 Lumia phone is running the most recent build of Windows 10 for phones with no issues. I refuse to pay a premium for the Apple logo, and Android is just a mess. Have an android tablet and even it can't update worth a $#!+.
