Let's think what professional users want from their laptops. I would say it's:
2. Easy and quick repairs if something goes wrong
Now let's look at these four factors with the new MBP:
1. Reliability - extremely low, there are a lot of components that can break and that do break (Bridge OS, touchbar, speakers, new keys), far more than the competition.
2. Easy and quick repairs - good luck with that, the superglued together MBP takes 5-7 days to replace at an Apple Store. Most other laptops can be repaired in an hour - swap an SSD and copy the data, or swap the keyboard for $20 at the nearest repair center. If this is a PRO machine why is it so hard to repair then?
3. Convenience - a ton of controversial decisions. Is the new keyboard better than the previous one? Do people need the touchbar? Where is SD card slot? Where is USB A slot? Where is MagSafe? A lot of them could have been easily avoided (eg Surface Book 2: no touchbar, great keyboard, SD slot, USB A, MagSafe - but admittedly no USB C)
4. Power - far less power than the equally priced Windows machines. GTX 1050 currently beats all the MBP graphic cards (hopefully Vega will be good), core i7 and core i9 really suffers from the small chassis. And yeah it's like $4000 USD for these models.
Overall - marketed as a premium device, but definitely doesn't bring a PRO experience. IF this was called "Macbook Experimental" I wouldn't mind, but for a pro machine, this won't do.
