I have a more than a decade-old iMac with a 27” display that I’m stil using as a monitor (though it’s seen better days), so that worked out well, but a Mac mini and an external monitor seems better in every way. Which monitor to get, though? Maybe Apple should sell a Mac mini bundled with a nice external monitor instead of iMacs.
