I don't see any closed system competing with open systems on a regular basis. I have to deal with windows for business reasons but there's no way I'm dealing with windows on a personal phone.
I just got a iphone 4 (not the 4s), after years with a Motorola non-smart phone.
It was mostly a matter of a free phone and a throw-up-the-hands surrender on my part because I didn’t want to fall completely behind the technology curve.
I have Windows on my laptop, etc., and now I am stumbling around with the iphone, which seems fine, if rather an overkill for my needs. But I am hoping you might tell me just what is meant by ‘closed’ system vs. open...sorry for my ignorance, and if it is more than you want to go into, no problem...thanks...
