I regularly use a pocket calculator: either a physical one, or Apple's Calculator app if I want more decimal places. 'Too stupid' isn't a thing for me if it can cough up some math that would be inconvenient for me to work out by hand. tok/s also isn't a concern because I'm not expecting more than I can read. My ideal scenario would be occasional diversions into querying a 'coding calculator' that can give examples along the lines I want, my way.
I'll make a mental note that Qwen shows signs of being the kind of calculator I'd use for a specific task. Context switching isn't a burden if you're not looking to switch over to vibe/manage and stay there.
