General comment for IOS, Android, Blackberry OS

Today the 3 OS have contributed the greatest technology and these are very competitive with smartphone market. The 3 OS are IOS, android and Blackberry. However, as a commentator and user of smartphone will explain and demonstrate the advantage and disadvantage of those.

Firstly, i bought Samsung galaxy 1 for the first smartphone and it was fabulous phone. When i used Samsung galaxy 1 was very good product and it is Android which easy to use it. In addition, Android OS is more open system than IOS;therefore, I found it easy to install some music,games and so on. Android OS allows users to be able to modify their own smartphone like their own PC. After a year, I gave it to my dad because Android OS does not has many application.

Secondly, I bought Blackberry because that time it was very famous in my country and Obama used it as well. In addition, BB was so famous in chating (BB chat). Actually, it is made for business people but most of teenagers use for chat rather than business purpose. I really thought BB is not useful product for me because the lack of OS performance, lack of technology, less application and hard to use.

Lastly, I never used Iphone before so i decided to buy Iphone5. I found it is very good technology and easy to use. IOS is closed system so i have install my music via itune. But the most i like about IOS that has many application. It also has many function and application to use in one mobile phone. So i do not need to buy a new smartphone anymore. I sometimes use some App to call to oversea, it is free. IOS may be the best OS for me now.
