The Apple Mac mini M4 is arguably the biggest bargain in computing. This (almost) pocket-sized mini Mac is fast, powerful, near-silent and costs around half the price of the cheapest equivalent MacBook Air. It's almost too good to be true.

I bought one last month, my first new Mac since the MacBook Air M1 in 2020, and it's given me that same sense of 'how did they do that?' wonder.
