Processing

• The computer's processor is essentially the brain of the computer, and the better features it has, the more efficient and productive your computer will be. For example, the Core i5, the Core i7 and the Phenom II are higher-end models that will enable a computer to process large amounts of data at high rates of speed.
  
  

Convenience

• Not all new features are necessary, but they can make your life easier. For example, the more memory your computer has, the faster it is. Instead of clearing space by backing up data on a CD or a USB data stick, you can instead simply have everything stored in one spot, alongside the basic advantages of having a faster computer.
  
  

Organization

• Newer features of many software packages make it easier for you to be organized. For example, newer versions of Microsoft Office now allow you to use revision marks on documents that need multiple edits. With this feature, you can track changes made to the work. Additionally, there is an auto-archive feature that automatically files away overly full inbox material to another storage location on your computer according to your preset preferences.
  
  

Productivity

• Having multiple tabs open at once is common for many computer users, but it can be cumbersome to switch back and forth between them when multitasking. In addition, things get difficult when you need to see both or all of the pages at once. Newer features, such as the iPad's Safari browser, now make it easier for you to view and use several pages at once; all pages you have opened are seen as thumbnails that you simply have to tap on to access.
