The GPU is not dog crap. It is in its prime.
Bought two MacBook Airs, one for my wife and one for myself. It hurts, but we of course maxed the RAM out to 16GB. The way I see it, if you are a busy multi-tasker, you simply have to.
Worst thing about Apple to me is that they really undersell you on the RAM and charge a lot to upgrade it. And it's the single most important thing I think you can use more of to get longer work life from a Mac.
The wife is a professional composer, and she does her own publicity for it. She's in and out of Adobe all day, as well as getting into Reaper as her DAW. It's been flawless. It edits Photoshop, music, and does video editing.
The problem is we're looking at technology for GPUs that is very advanced. Obviously we're not going to squeeze Nvidia 3090s on these machines. But the need for high-end GPUs is so very, very, very niche. These accomplish the biggest need for GPUs on an ultrabook-sized laptop. It gives proper hardware acceleration to production tasks, and I can zoom or watch youtube without it sounding like a jet turbine or scorching my lap. which is more than I can see even for the current 11th gen Intel laptops or Macs from even a couple of generations ago. This Air is a better pro production machine than anything not in a bigger, heavier chassis. And it doesn't even have fans!
GPUs certainly are needed for higher-end video and effects rendering. And that's not nothing. And it is a terribly frustrating time for professionals as the supply is completely constrained by people "mining" their ephemeral Dunning-Krugerrands.
Gaming is incredibly frustrating, too. But I'm also maybe a typical Mac user in that I can take or leave most gaming. (I was getting into Warframe with my 1060 card up to a couple of years ago.) But the high-end cards in short supply, and top-tier games requiring so much beef for rendering AI in blades of glass and light reflections, as well as consoles now in short supply, gaming really is in gut-check time. I actually think the M1 points to a fantastic future for gaming. Not necessarily on Macs, but possibly there, too. But the efficiency of ARM is now so proven, we're going to see AMD and Nvidia race very hard to use the big-little processor utilization in ARM or ARM-style chips. The fact that a game actually optimized for the Mac M1 can look just fine (like WoW?) means that this is just the beginning of some great things for this design.
