I wish I could remember where it was at, just within the last week I recall reading several unfavorable opinions about System 76. It was either here, on Reddit, or the FreeBSD forums.
I had been considering one of their laptops due to the apparent extensive Linux support and wonderful "unicorns and puppies" praise on some of the Jupiter Broadcasting podcasts (until it hit me that System 76 is a huge sponsor and so they wouldn't be saying anything negative about them) but the comments I just read caused me to strike them from my short list.
