Why are computers so frustrating? -- If you find PCs frustrating and confusing, you are not alone. When the Personal Computer was introduced it was a simple. Since then, it has really grown into a complex “Business Computer.” Almost every business uses these “PCs” for Accounting, Engineering, Graphic Design, Databases, and hundreds of other business applications. The PC has moved far away from its original Personal Computer roots. To support these millions of business applications, the computer is complex. Businesses need IT teams to help employees use these computers. If you are still using computers at work, the business computer may be a good home computer since you are trained to use it at work.
