As a user and programmer, I can only dream of being this knowledgeable about things. There's a ton of domain knowledge embedded in the article, it's pretty amazing.
I managed to reverse engineer a lot of my laptop's features but hit a wall when it came to this ACPI stuff. I dumped the tables and decompiled the code but all I got was stub code. I wanted to be the guy who wrote the Linux drivers for his own laptop but I just didn't manage it. Massive respect for anyone who can do this.
Yeah the best way to go is to buy Linux preinstalled and supported. Though, as with Windows in this case, that still won't save you if the system integration and firmware teams don't do their job.
