I would say I am a "pro" user by almost any definition. Apple and Adobe have been my sole source of income for 25 years! What I saw at the roll out:
- Emphasis on "thinner/lighter". (Not sure why that matters, especially to a Pro user? I have never had to slide my laptop under a door - thickness and weight not an issue)
- Touch Bar is "cool" has some possibilities, but Emoji's for the big demo? (I am in business with over 100 business clients and corporations and have never used an Emoji in my life! Pros don't use Emojis in business correspondence!)
- The Photoshop demo - she mentioned it was a lot like learning to play a musical instrument now between the touch bar and track pad (That is what I am looking for - something else to "learn"! I am ready to take the challenge using key commands and my Wacom vs that method demonstrated)
- Skylake chips - (All that one can expect since the timing was probably rushed for the XMAS season?.
- Soldered (and not the best) RAM - not acceptable. (a Pro machine should always have user upgradable RAM. Soldered-in should be reserved for cheaper disposable machines).
- User swappable SSD Drive - this may not be an issue based upon the OWC report?
- Loss of dedicated built-in MagSafe connector and extension cord. (Mystery)
- Obvious missing built-in ports over what I have now in my 17" Macbook Pro w/DVD. (But this is apparently the new Apple philosophy - even with the Mac Pro trash can - make everything as small as possible, solder everything in and then have an octopus of cables and wires all over the desk)?
- Then what every Pro needs - Siri integration. (What Pro does not want to shout at his computer just to annoy anyone else in the vicinity (aka Smartphones).
In spite of all this, I was ready to pull the trigger at the announcement, but just could not justify the price all things taken into consideration. Maybe next time.
1. It matters to me immensely because I have to carry it potentially many hours a day on my shoulder. Why should I have to carry needlessly heavy gear?
2. Actually pretty much every developer team i've worked with have made liberal use of emoji on internal communication channels, (i.e. Slack, GitHub etc.)
3. Don't like it? Don't use it. Not every use of the touch bar will require coordinating your hands like that.
4. Sure in a perfect world we would have Kayblake - but with Intels recent history we'll probably have to wait 6-9 months for Intel to get their **** together and release 45W KabyLake chips. People were already going insane waiting for the past year+ for the update. KabyLake doesn't provide enough to be worth waiting for IMO. The next node shrink etc. should bring a lot more to the table.
5. I mean sure more than 16GB would be great, but not that necessary for even most Pro users, despite their insistence that they can't get absolutely any work done at all with less than 64GB. Used to be many years ago just updating the OS made you double the ram just to do basic tasks, but the past 5 updates haven't really moved the needle in that respect. Lots of Pro apps have gotten more efficient with memory over time, and macOS has many sophisticated ways to use and free up memory.
6. Like you said maybe not an issue. For me personally the 512GB is more than enough for my needs for the foreseeable future.
7. The griffin one will probably be updated (or description updated) to support the 85Watts on the 15" Pro if you really need magsafe. I think the power charger's design is a lot better now, no need to replace the whole charger if the cord frays, the ability to choose a cord with a longer, or shorter, or more robust one. Having never used the extension cable that came with my previous systems I'm not upset about it not being included now.
8. I can plug in a hub and have many as many ports as as I need - that is IF i really wanted to. Fortunately i've been investing in the future and have no need to plug almost anything into my MBP when it arrives. Just a USB-C to Lightning for deploying builds to iOS devices.
9. Then don't use Siri.

Not sure why this is in your list of things you dislike about the new MBP since Siri isn't tied to the MBP in any way. If there was still no Siri when Sierra came out then people would just bitch and say Apple was behind Microsoft, etc. I don't use Siri when in my current office environment (especially because it's a horrible "open floor plan" type) but do - occasionally - when at home.
