Posting my experiences here for anyone worried about 8GB on the base MBA.
I picked up mine yesterday, having decided to take a RAM gamble (RAMble?) and cancel the 16GB I had on order. It's the $999 model.
I'm a heavy user but not a photographer/videographer - so think multiple apps open all the time:
- Brave with 10-20 tabs, ranging from work tabs such as Facebook Ads and Wordpress to, ahem, MacRumors
- Superhuman
- Slack
- Messages
- Music
- Alfred
- 1password
And some opening/closing throughout the day:
- Whatsapp
- Notes
- AdWords editor
- Zoom
- Github
- Terminal
- Sketch
For my workflow using the apps above, 8GB feels more than sufficient. My day-to-day machine is a 2020 iMac with 40GB RAM - the M1 MBA feels exactly the same, if slightly more responsive. From the few times I've checked Activity Monitor (and bearing in mind the discussion above), the memory pressure has always been green, with ~6GB in use, and ~2GB cached. FWIW, I also have a 2017 3.1GHz MBP with 8GB RAM, which feels frustratingly slow by comparison.
Side note: I unboxed this thing at lunchtime yesterday - it's now 11:35AM and I haven't charged it (I did go to sleep, obviously).
Top-line: For people with similar browser-heavy usage requirements to mine, 8GB *should* be OK. I can only assume my experience would be slightly better were I using Safari, and that it will improve once Brave gets a Universal update and Electron apps such as Slack and Superhuman are ported. I feel like the gamble (which saved me a couple hundred dollars) paid off.
HTH.
