OK, I'll bite. I'll talk about the Mac Pro news.
First, I'll state the obvious and applaud Apple for conducting a "Mac State of the Union" with a Congress of the Apple press. Bravo.
Looking at the details, I think we should be careful when assessing the use of iMacs, laptops, and Mini's by the pro user base. Specifically, were these folks running to the pro merits of these other devices or running away from the lack of a viable Mac Pro option? I think the latter.
I'm a Mac Pro user (2009 5.1) and devotee. I also own a top-line 5K iMac. I'd much rather do heavy computing on the Pro. For one thing, even something as simple as playing a 1080p video on the iMac wreaks thermal hell and sends the fans into overdrive. My oldish (and well-liked) Macbook Pro did similar things.
But what I truly like about the Pro is its easy expandability. In fact, I wish that it had more slots! Mine are always full (and I still lack a fast flash disk card).
So I am very, very psyched about the announcements. I am hopeful that the 2018 offerings are not outrageously priced.
Finally, as an aside, those who just can't wait until 2018 have an option. Very decent Mac Pro towers can be had used in the $1K-$2K price bracket. Maybe less if you mine Craigslist. If I were in the market for a non-laptop Mac, that's what I'd do.
Note that I am not trying to criticize non-Pro Macs. I just wanted to contrast them with the Pro, hopefully highlighting the latter's merits.
