Whilst the M2 might be a great chip, will the hardware still ship with 4GB of slow than congealed molasses? When is Apple going to produce fast RAM? 1066 Mhz is slow, 2133 is just a tad better, where is the 6000 MHz or greater?
Which is better, more RAM modules of a slower speed, or fewer modules of a faster clockspeed?? And what would be best for video editing on a laptop?
If you're video editing on a laptop, then a Macbook Air is not the laptop for you. Apple has made that perfectly clear over the past 13 years, let alone made it perfectly clear which Macbook you should be getting.
Personally, I thought that I would only be doing basic work, so I picked up the mid-2011 MBA by choice. Word processing, simple accounting on a spreadsheet, and getting back into MacOS after being a Linux guy and last using System Software 7.5.3 on the last Mac I had. Insert livestreaming and virtualization later, and I realize that the MBA wasn't what I needed. I'm still on it until the right MBP comes out, then I'm jumping to the MBP for the exact reason you are asking.
Need to video edit? Macbook Pro. Otherwise, you'll be complaining about the same thing everyone else has been complaining about for the past 10 years while not understanding that the MBA isn't targeted for you or your needs.
