My wife bought a Neo and has been very happy with it. I was wary of the 8gb memory limit but she is running claude code doing web development with a reasonable number of tabs open and no noticeable lag, so I'd say its definitely getting a lot of mileage out of it.
It honestly seems good enough that it might cannibalize Macbook Air sales.
I am running Claude Code, Claude Desktop, Codex and Docker Desktop on a last generation Intel Air, that admittedly has 12 GB RAM. One has to be a bit careful with more apps. But I look forward to an upgrade. Maybe a Neo, but more likely a second hand M.
It might be more likely that it cannibalizes used Macbook Air sales.
