I believe this is an option for a backlit keyboard on some of the models. Prior to this machine I'd been using Mac laptops back to a G4 PowerBook (2004) to a 2011 MacBook (last release pre-retina display). While my current laptop isn't as polished as an Apple, I wasn't looking for one. The screen wasn't a step back (I know from screens I've published in peer-reviewed journals on them) and the keyboard better than the MB Pro -- the speakers are about as good. The major negative is the mic placement on my machine -- beside the trackpad. I think this is a quirk of the model I bought. The touch pad is really nice, more sensitive than the MBP and flush with the body (a nice touch). I was generally disappointed with the 2011 MB Pro on battery/power issues -- the battery life wasn't great and it ran too hot most of the time. Buying a System 76 laptop was the last step on a long road from being an Apple fan who played around with linux to finally embracing linux as good enough for everything I do now. There's a nice touch here or there that I miss or some quirks that I know exist because I've left the walled garden, but I am glad not to be forking over cash for Apple's corporate shenanigans and to be supporting a small company.

System 76 has some good options -- I bought one a year back and haven't regretted it. $500 cheaper than a MacBook with similar specs.

It isn't the most elegant post but the mods definitely need to mod this up. The idea that neuroscience retreads the ground trod by cognitive scientists, psychologists and psyhcophysicists is essentially and profoundly true. Take the case of light detection where a study by Hecht, Schlaer & Pirenne done with psychophysical methods in the 40s estimated the minimum number of photons needed to detect a light. This result was only "measured directly" by neuroscientists in the late 1980s. Color vision is another example. Well worked out by psychophysicsts long before neuroscientists could say anything about opponent colour channels in the brain. There's been a recent bias to laud people who stick electrodes into cells... but this doesn't make the science particularly ground-breaking.
