You know what ? I was not even aware that it would work ! (Am I the only one to discover that just now ? I am not using Spotlight very often)

It's kind of cool, but I can still find many grievances about the way it's done :-)

I’m sure it’s not ideal, but for my purposes cmd-space (random math) is generally sufficient. But I’m also not a mathematician so I do maths with numbers and not letters :)

Even with numbers only, it can still be useful to know how wrong the result is. Chalk keeps track of every inaccuracy when dealing with decimal numbers.

Oh yeah, I very much use it as a super quick access calculator. If I was needing in a situation where I needed controlled error etc it wouldn’t necessarily be great, but that’s ok because in general if you have me working on something requiring that your project has other issues :)
