This: comparing something you buy once, with a license does not make a lot of sense. In SaaS, you get update, support, etc. For something critical, I'd rather get that than something that I buy once and may be buggued in the future.

I think you're right. I'm not an Apple fanboy (by far), but I'm very excited about that product for nomadic work purpose. I like to move a lot, and being able to work without having a desk or similar is incredible. I'm just a bit skeptical about a few points rn: that it isn't comfortable when the weather is hot, that the battery is bulky or doesn't last a day... but so far I've read everywhere that the tech is incredible.

I know this is a piece of humor, but half of these are not surprising coming from a FP background (expression oriented, sum types, strong generic typing... )

Also, daring to compare Go and Rust error handling, and saying that Go's one is better is... bold. It's arguably one of the worst in any language.
