Should you still invest in Apple?
Today I had a thought - should we still buy Apple shares? After all of the controversy and all of the instability displayed by the company, are we still to trust Apple or are we to stay away from it? 

With this question in mind I decided to venture onto my own little research and after I have found my answers I decided that you ahould have all the information too. After all, we want you to be as successful as you can. 

so, here goes. Should you still invest into Apple?
