I opened this bad boy up last night! Specs are in my sig. This is my first Mac, upgrading from a Dell Studio XPS 1647.
I love the keyboard so far. Plenty of travel for me. The Touch Bar makes making little adjustments like screen brightness and volume a little less immediate, but I'm sure I'll get used to navigating the Touch Bar more efficiently. Things like FaceTime answering and emoji seem so natural on the Touch Bar, like that's where they're supposed to be.
I was simultaneously downloading WoW, Lightroom, Spotify, etc. and the thing got pretty damn hot. Right in the dead center, above the Touch Bar was almost alarmingly hot. The fans finally kicked in. Damn those things are quiet. I'm not sure if they were on max speed, but I could barely hear them. Then I put on Spotify... DAMN those speakers are loud. Like, 80% volume was physically hurting my ears. They sound great.
FaceTime camera is a bit disappointing. My GF said the iPhone 6 Plus looked better when we swapped back and forth.
Then I fired up WoW. I had to turn on Metal and then restart. The first thing I noticed was how saturated the colors were... like almost-over saturated. I changed the resolution to something just a bit over 1920x1080, since I'm used to that res anyway. I put the settings to 5/10 and tweaked a few more. I was getting about 30-40FPS just in general questing areas. I was expecting a little more. I'm used to playing on the lowest settings, so I'll take any improvement. When my new mouse comes tomorrow, I'll do a raid and see how that goes.
I did some Lightroom work this morning on the train. It was so effortless to take it out and go through some wedding photos. The 15" size is perfect for me; 13" would be too small. My photos look AMAZING. Like... the RAW photos look almost good to go as is, like I shot them with a new camera or something. I can see clearly what's in focus without zooming and it's awesome.
The size and weight comparison to the XPS 1647 is laughable. The smaller form factor and 2.5lb weight difference made me think I forgot my machine this morning because my backpack was so light.
