Yes, although its a pity that we didn't see iMacs and laptops with 6-core Intel 8th gen processors at WWDC this year, that only puts them a few months behind the curve - and they may be waiting for the appropriate CPU variations to become available in quantity from Intel. I don't think that's what people are getting riled about, though.
Last year's iMacs were pretty solid machines - I've got one and am generally happy, although I'd have preferred a modular desktop, my choice of screen, and twice as many ports.
The iMac Pro looks great if you want a $5000 computer where you can't change the screen or have a realistic choice of GPUs (...and if you go for an eGPU, that makes the internal screen
with no external input look increasingly silly).
No, the problems are (a) the Mac Mini and Pro models that are important bricks in the line-up but which haven't been updated since 2013/2014 and (b) the lack of a proper "pro" laptop, not compromised for size and weight, to tempt all of those people still rocking 6-year-old MBPs. The new MBPs are lovely ultrabooks (if you work in a cleanroom, wear a hair net and wash your hands before touching the keyboard) but simply not what some of us (including those of us who shake the cookie crumbs off the keyboard every few weeks and have never had problems) want or need.
AFAIK all they have said about the Mini is "
the Mac Mini is an important product in our lineup" - which, I'm afraid, sounds very much like corporate-speak for "what's a Mac Mini...? Hey, Tim, do we make something called a Mac Mini?" A truly important product in their lineup would have been upgraded since it was last
downgraded in 2014. There have been several generations of intel NUC computers since then that show what a Mac Mini
could be.
...and we still have absolutely no idea what the new Mac Pro will be, or
when in 2019 it will appear, and the current Mac Pro is an expensive dead duck that even Apple have admitted is dead... which is a bit of a problem for, you know,
pros who might have deadlines to meet and spending plans for next year to prepare.
When products have been allowed to go to seed for so many years, its easy to be cynical about promises that don't come with tech details. There
should have been a Mac Pro pre-announcement at WWDC even if it risked a short-term dip in iMac Pro sales - long-term, pro customers who need
some sort of long-term certainty will now be walking away and, once they've made the effort of switching platform, they won't be walking back.
