RE: Apple or Other Companies? Why?

Apple currently owns more than 50% of the market share

This quote is wrong. Apple doesn't have 50% of the market share, they have more than 50% of the industry's revenue, which is different. Market share is almost a monopoly for Android.

Are you using an Apple product? why not other companies who mostly provide the same service/product for cheaper prices?

Yes, I am using Apple products. My next phone will probably be an Android but Apple products are better because Apple easily integrates new features into its entire line of products, Android doesn't always work as good and the implementation of new features in Android isn't as smooth. Also, iOS is a very secure system while Android has a lot of horror stories from all sorts of hacking. iOS respects privacy, for the most part, Android doesn't.
