I don't really understand all the comments about how 8GB isn't sufficient and how 16GB is the MINIMUM many of you would consider. For heavy power users, sure. But is everyone really a power user?
I'm not a power user, but I do tend to open way too many tabs and leave a lot of stuff running simultaneously.
My 8GB M1 MacBook Air easily runs 25-30 Safari tabs, MS Outlook, Excel, Word, Apple News, the Dropbox client (Intel client - not native Apple silicon), etc. simultaneously and hasn't skipped a beat. I have all of this open as I type this. My memory pressure stays between green and yellow and my swap stays in the 0-100MB range. I haven't noticed any hint of a slowdown whatsoever.
No, I'm not doing gaming, video-editing or software development. If I did these things, I'd probably need to close a few apps down that I didn't need running.
I considered getting a 16GB MBA. But with Christmas sales, I was able to get a base 8GB model for $799. Due to the sale pricing, the cost difference to upgrade to 16GB (a custom configuration) would have been pretty significant. So I decided to grab an 8GB base model from Costco and try it out. I have 90 days to return it. So far, I see no reason to however. It's a great machine and meets all my needs perfectly well.
Just wanted to add another perspective. Yes, if I could have gotten a 16GB model for a small upcharge, I probably would have done so. Would it have made a difference in my case? Probably not. But going from 8GB to 16GB would have been a minimum $300 price increase due to the sale pricing on the base model - a 38% increase in cost. If I decide to upgrade to the M2 MBA in 2022/2023, I probably won't take a large hit if I sell my base 8GB MBA since I got it for a great price.
