I am an IT professional who has worked with some of the most powerful and complex computers in the world.  My experience spans 20 years and I have done everything from repairing computers (component level on laptops all the way to malware removal).  With that said, I have had an opportunity to work with some of the best and worst in computer systems and manufacturers.  I can easily tell you that Dell is one of those manufacturers who have managed to stay in my top of the list for personal computers and business systems.  Zones does have an issue with selling Dell products and down-talking them, and it is simply because they cannot get high commission off of those products.  Dell will sell their products for far less and make much higher profits through their direct sales channels and other VARs such as Newegg and CDW.  Your understanding of the quality of Dell's products is completely uninformed.  You were given a bunch of propaganda during your relatively short training period at Zones and were told to say certain things about Dell that just isn't true.  To be honest, I would rely on a Dell product over HP, Lenovo, Sony or Acer any day of the week.  

Truth be told that Lenovo's reputation for high quality desktops and laptops is quickly eroding due to their constant deviation from IBM's original designs, and HP laptops always have and always will have serious cooling problems that result in GPU failure on the motherboards.. This is a known FACT.  Sony uses foxconn motherboards which are garbage, and so does HP.

Dell is the only one who consistently uses quality components, which although some of those components are manufactured in China, a lot of them are still manufactured in San Jose, California by Supermicro.

Get your facts right before you start attacking things you know nothing about.
