I'm a tremendous fan of Dyson Cleaners, but let's face it ... they are expensive. Why is it that there are some items that seem to retain value over many years and hardly ever go on sale? And why is it only true for certain items? Of course there are disruptive technology, social, or political changes that occasionally disrupt this phenomenon; but yes, some items just hold their price well and never seem to be found on sale (at least not a very good sale). Let me share with you 3 reasons why Dyson vacs are never highly discounted.

Many consumers will simply look at the Point-of-Purchase cost (what you pay to buy an item) and not factor in the long-term consumable costs when making a purchase decision. The selection of vacuum cleaners in the United States has been distorted by such marketing tactics. I am not only a huge fan of the Dyson because it makes engineering sense but also because it makes sense financially.

When you view a vacuum cleaner the way an engineer views it, you'll see that a vacuum cleaner is very effective at pumping allergens into the ambient air and at aggravating allergies. Dirt, dust and allergens are drawn into the vacuum bag by the vacuum motor. Similar to how water in the kitchen sink drains more slowly as food particles fill up the strainer in the kitchen sink, the vacuum bag can be described as a variable flow resistor that makes air flow more and more difficult as dirt is accumulated within the bag. The most unfortunate issue with a conventional vacuum cleaner is that the smaller particles that typically escape most vacuum bags are the ones that cause the greatest problems.

One of the fundamental problems with the conventional vacuum cleaner is that as you use the vacuum cleaner it fills up with dirt; and as it fills up with dirt, the dirt clogs up all the pores of the vacuum bag and restricts air flow. What this means is that if you use your vacuum even just a few times, the vacuum that you're able to generate can drop by by 30-50% with just the first few uses and then drop to a disappointingly low value as you exceed 1/3 to 1/2 of the bag capacity. The beauty of the Dyson is that there is no bag at all - no drop in vacuum suction and no bag to buy.

The Laptop Dilemma: When using a computer, you typically want the monitor to be around eye level to encourage good posture and the keyboard should allow your forearms to remain parallel to the floor and elbows at the sides. The problem is that the monitor and the keyboard on a laptop are typically joined together, and it is impossible to position both the keyboard and the monitor properly ... at least not at the same time. This article provides some tips for laptop usage that will help minimize the risk of serious ergonomic injuries.
