Re: Perhaps realising that there are times of day and places where.............
Indeed - given how Apple users seem to walk around holding their iphones in front of them all the time, it doesn't seem surprising. Another thing I note is how Apple laptops users seem far more likely to carry their laptop everywhere they go, where as most people usually leave them at home, or keep them carried in a bag if they're travelling.
Not to mention that Apple products are plastered in obvious logos (in some cases light up!), which helps advertise that you have a product. And that Apple products are only ever in the expensive range of the market. Personally I prefer my phones, laptops etc to have as subtle or unobvious a logo as possible (plus it just looks better that way - same reason I don't wear Addidas clothes).
Though it's great for Apple because it's yet more free advertising from the media. Just check out stories on thefts - it's always "laptops and Ipads" or "Macbooks and phones" or "Iphones and tablets" - if there's an Apple product stolen, it'll always be mentioned by name, like some kind of product placement ad, whilst other products are just mentioned generically.
