I hear you my friend! As a graphic designer and fledgling app designer with occasional video projects, I need more grunt than most current day ARM processors/devices for prosumers. I mean I love my 3 year old 12.9" iPad Pro (never stutters, never slow, only gets warm playing World of Tanks on gonzo quality). But games are already getting fewer and farther between for MacOS… otoh I played the iPad demo of CivVI and was surprised at how well the whole thing ran (but the UI wasn’t as fun and I’m already tooled up on mac Civ on Steam). It’ll be a rocky transition but maybe parallel Intel/ARM macs will be the best of both worlds? mb light a fire under Intel’s posterior…
Where I see this taking things to a whole new level is the iPhone becomes your Mac when you come home and plug it into your giant screen (which may have a slot for a co-processor?) Joe/Jane Shmoe’s average workload is surfing the web, email and some light video editing or social blah blah. I noticed the dev kit did NOT have Thunderbolt3 or USB4 listed… think what a monster of a product that would make: a phablet that you just plug in to your 4k or 8k giant format USB4 screen/hub and it all just works. Not sure wireless could compare to TB3, but some functions could be wirelessly enabled (ie you come home, the NFC unlocks your door, BT pings your screen to wake up and connect to the phone via Wi-Fi and start handshaking.) Your iPad is a phone and mac and pen enabled tablet… throw in AppleTV and make it just one more HomePod node. I’m getting tingly.
