If you're buying for business, you can generally speak to a US sales representative -- or if you have Pro/Gold support on an Optiplex, Precision or Latitude system. Consumer support (Inspiron/Vostro/most XPS) is offshore -- as is sales.  You may do better buy purchasing from an authorized retailer (Best Buy, etc.).  
Unfortunately, I am unable to contact a customer support person I can understand well enough to help me purchase a computer. Is there a phone number I can call in the U.S.?    After reading some of the comments, I am hesitant to continue on with Dell even though I have purchased multiple computers from this company.
