Anyone who is very excited for this doesn't respect any choice. Their all Macbooks are having soldered POS HW from SSD to battery, KB. They even made an Intersil chip not available on the market for repairs, to force users into their repair structure with insane revenue.
Anandtech SPEC is useless as a whiskers on a cat, that ARM processor in an iPhone cannot do anything that an Android 8 phone does (not calling 9 and 10 because they started to copy that Scoped Storage BS which is shutdown filesystem, like UWP), all that processing power is used for iMessage, IG, Snapchat and other social media garbage with some stupid Pubg and other mobile trash games by Tencent. And that iPad got a downloads button very recently so did it's new Control Center and all. Plus their iPhones lost to OnePlus and Samsungs in the applicaiton loading, and other real world usage tasks with Throttling as well on load (GFX usage) and their famous Batterygate, Butterflygate, Touch Disease, and other ton of issues carefully thrown under rug due to their deep pockets. Their Catalina gatekeeper is hard to allow other apps not signed and then their 64bit hammer. People who are using that Hackintosh will be nuked as well, I thought that time would come when their security through obscurity masterplan T series chips in the Macs with handling all the I/O tasks, making an x86 just a slave processor for the execution.
Anyways I think this will be new Mac Air, a shame that AMD is still wanting their money for those rebadged trash GPUs. Glad that Apple failed in gaming, their AR is useless. So ultimately their Software will be made to work properly because they pay Adobe a ton to make the software optimized like First Party solutions. So that's also an expected thing. All in all it's just going to make Apple keep more money, the more greed the better for them.
x86 is not going anywhere and it shouldn't as well, the garbage ARM is always custom, look at that SQ1 garbage in Surface (full BGA trash boook with no 3.5mm jack either and nothing can be serviced in that garbage, not even LTS release), Server side also Graviton loses to EPYC7742 in many tasks that is also an Amazon's internal cost effective solution, the fact that x86 processors are going to innovate (thanks to AMD) we can enjoy Win32 more with choice.
