I live in LA and work in the Entertainment business. I've seen two Watches ... one in my gym, once; and the other on a guy on a plane who may or may not live in LA.
Considering LA and the entertainment business in general is on the cutting edge of new tech, and now that the delivery times on the Watch are down to a day for almost all models, I'm really stunned that I haven't seen more after almost 3 months (especially when LA had the only store in North America that actually sold them from day one). It suggests to me that there's a completely different demographic that's embracing the latest Apple product this time, and fashionable and trendy LA is not it.
