This just struck me.
If you don’t have an Intel-based Mac, it might be a good idea to get one. The reason: They’ll run basically everything (MacOS, Windows, Linux) thanks to such things as Parallels.
The new Macs with the Apple Silicon will likely be faster and run longer on battery but are unlikely to be able to run Intel Windows.
Probably the optimal time to get one is when the new MacBook Pros are release (likely later this year).
