Clean install, fresh out of the box. Only things loaded are the App Store, iTunes (with no music loaded yet), Calculator, Messages, Mail, and Safari (no extra tabs). Note the memory usage. Remember, I haven't even installed any productivity apps, and haven't even launched other iLife apps (besides iTunes) or iWork apps. Guys and gals, if you can swing it, get the 16 GB, especially if you plan on keeping it a few years. --- The keyboard is way, way better than the keyboard on the 2015/2016. Still not my favourite keyboard, but I really disliked the keyboard on the 2015. Trackpad still isn't as firm (on the firm setting) as the one on the MacBook Pro. I don't notice any difference vs. the previous model MacBooks. It actually feels faster for navigating around the OS and surfing than my quad 2.93 GHz Core i7 870 iMac, but then again, that machine is using a FireWire 800 SSD. (The internal HD is even slower.) Meanwhile, here is my MacBook's 256 GB SSD (which shows as 250 GB): Of course, it feels tremendously faster than my old 13" 2.26 GHz MacBook Pro from 2009 (with SSD), but it also is noticeably faster than the 2015 MacBook m3 (from my limited testing in-store and with friend's machines).
