"Professional" isn't about synthetic benchmark scores, sometimes.
Things I'm getting from my Dell that I can't get from a Macbook:
- Docking station. Yes, I care. I like to have a setup with a bunch of stuff plugged in. That theoretically next year sometime there might be a TB3 dock on the market that can do most of it eventually with a cable is neat, but it's not a real replacement.
- Non-glossy screen.
- SD card reader and various ports I actually care about. Just Works with the things I want to connect it to.
- Function keys, key travel, and numeric keypad. (I admit, I could live without the keypad. I can't live without the function key row and the key travel.)
- Enough memory to run large VMs, which I sometimes want. (Has 32, upgrades to 64.)
- Can have two storage devices. (Currently two SSDs. Both user-upgradeable, so next year when SSD prices drop, I can upgrade further if I want to.)
The benchmark doesn't cover things like "can I have 4TB of internal storage", or "how does it do at running two VMs, each of which has 16GB of memory, simultaneously".
And yes, I've actually had the 2016. Several of my Mac-user coworkers have too. The net result is that company policy has changed, and we won't buy any more 2016s unless Apple fixes stuff. Mac users are going to be getting 2015s. And the people who got the 2016s all agree that this is a good decision.
This machine is sorta crap.
