I have an M1 Pro 64 GB RAM, 2 TB HD. I run 3 external monitors with trading software but everything still seems smooth. I'll code with Cursor, and with Claude CLI in the terminal, and also have open Wispr Flow, Music, Messages, Quicktime, and also have probably 20 Chrome tabs open for various online apps like Replicate, OpenAI, Grok, X, Gmail, etc, all while the 3 monitor Thinkorswim runs... Nothing feels slow until I have around 50 Chrome tabs open which of course is too many anyway. I do move around with the laptop often so am planning to probably get an M4 Macbook Air or an M5 Air when they come out, but will keep the M1 Pro for trading given the 64 GB RAM and the monitor ports. Happy to be persuaded otherwise though. Perhaps it's the old situation that nothing feels slow or laggy until I experience what fast(er) really feels like?
