Dell: Known for Using the Cheapest Components

I’m listening to a CNet reporters round table and I’m hearing that Dell is known as buying the dirt cheapest components. Lenovo buys the Cadillac of components (I’m not sure if this applies to their Lenovo brand or only the ThinkPad brand)
Listen to the round table here, and get INSIGHT into HP (why it’s seemingly doing well) and why Dell is “apparently” not doing os well.
These things are important for you to know as you decide what company to buy from.
