Different shapes, sizes and uses

Computers are being used in many ways these days. I just met my wife at an appointment she had and I was fascinated with some of the systems I saw while at the doctor’s office. I am not going to go into the detail of the type of system except to say that regardless of the uses, they still have monitors, keyboards, mouses and disk drives. Many uses, but, but in a way they are all still the same, just different shapes, sizes and uses. Whenever I am somewhere and I see new systems, I always get lured to them.
