Early computers were aimed to perform mathematical functions but with the passage of time this all changed and now we use personal computers
in a variety of tasks. They range from business applications to personal entertainment and the size of computers has come down significantly as well. But technology was still ugly until Apple Inc. came along and changed it all for us. It devised computers which were aimed to multi-task and packaged this in a beautiful UI within an operating system. This led to the invention of the first MacBook which has now become a rage among computer and laptop buyers. Based on the OS X, these laptops are a thing of beauty and this is why this operating system is the second most used OS around the world. Even though this brand has come up with a lot of different Apple MacBook series in the past, it now offers only two of them which are Pro and Air respectively. When compared to other brands which manufacture Windows based laptops, Apple chose to instil multiple features in its computers because of which the Apple MacBook segment became highly popular. The Pro 15-inch Retina for example is a feature loaded laptop whose specifications are Quad-core i7 2.7 GHz processor, 16GB RAM, 512GB Hard drive, In-built Flash and HD Graphics 4000/GeForce GT 650M 1GB graphics card. Under the Apple MacBook Air series, 13 inch MD232HN/A is highly popular. It offers 1.8GHz dual-core Intel Core i5 processor, 720p FaceTime HD camera, 256GB Hard Disk Capacity, HD Graphics 4000 and 13.3 inch Retina display.
