Adopters of products that are new, are divided into groups of when they adopt new products.  Innovators are the first ones to adopt a new product and they are always looking for the next new thing to get.  This gropu has the smallest percentage of consumers.  The next category is the early adopters, whom of which will get the new product after much research and they are careful in choosing these new products.  This group is closely watched by marketers, since they indicate whether or not the new product is going to work.  This category consists approximately 13.5% percent of the consumers.  The next group is defined as the early majority, in which these consumers adopt a new product quicker than the "average" person.  These consumers are also careful and do their research before choosing the new product.  This group accounts for 34% of consumers, as well as the next group, the late majority.  The late majority are skepitical of all new products, but eventually give into getting new products because they may have to get them.  The final group of adopters is considered the laggards.  This group is the last of which to adopt the product.  Sometimes they are so late to adopt a new product, that there is already a newer product that may replace the one they just adopted. 

Those people that stand in lines to purchase the newest gaming system would be considered the innovators.  Those of which that purchase the product after the initial date that the product was introduced, and have done some research would fall into the early adopters category.  The early majority would probably purchase the new gaming system within a year of when it was introduced, and the late majority would buy it after that when its probably cheaper, and a lot of people have already purchased the new gaming system.  Then there are the laggards, like me, I just purchased a PlayStation 2, and I guess its been replaced with a PS3 a long time ago.
