It will not take away any business after the first few idiots will lose the drone in the stronger wind it will be back to usual. I don't think we should have an approach: "It is small so if it hits someone it is ok" we should be avoiding accidents by flying in good conditions. Not by flying anytime and saying: if I hit that lady with the kid it's ok the drone is light and most likely will not do any harm.
There are not many days in a month in Canada when you can really fly MM safely to do the job.
I have MM since day one and flew bigger drones and have a quite good comparison. I think when the client wants to do the shoot on Wednesday, you go and do it on Wednesday, how many times you will ask to reschedule due to windy weather. You might have more flexibility with real estate, but how are you gonna go about weddings etc, I'm not even mentioning any type of surveys, you gonna say: If the weather will be nice you will have your drone shoot?
Come on, that's just not professional

Mavic mini is a toy, it does what it does in certain conditions, but it is a toy, anyone trying to use for building serious business is delusional. As an odd addition for one-offs sure. But I already heard here it could be used as a rescue drone, so nothing will surprise me

There will be more people with "I lost my drone on the first take off"
