I want to start with macbook pro retina, but it is mainly used in office areas such as document processing, and sometimes I do some photography videos. How simple is it to use?

Macbook pro retina screen has high resolution and positive color, which has great advantages in video and photo processing. Microsoft provided an upgrade patch for retina in Place 2011in 2002, which improved the weak font of non-Retina version of mac. Generally speaking, your needs are completely satisfied, and your usability is better than that of windows.
