I was thinking the same thing.
Those categories are the perfect way for brick and mortar stores to differentiate themselves from online retailers. They're accessible enough that the average consumer may be interested in them, but complex enough that you'll probably need advice from someone knowledgeable before buying.
I'm really surprised Best Buy hasn't devoted much (if any) floor space to those things. I bet they could sell truckloads of things like micro FPV drones if they just demonstrated them for customers.
