What's the difference between a MacBook and a MacBook Pro then? Both are similar and the Pro model doesn't really have Pro features as such. I get your gist though.
I see it that the MacBook Pro is a device that was created for productivity per the user to complete more desktop orientated tasks and or programs. I don't see an iPhone that is meant or intended to be categorized the same as a MacBook Pro. Especially for a device that is updated annually with Certain capabilities.
