An IT technician will come to your business to resolve the problem one business day after diagnosis _________________________________________________________ My personal experience with Dell Tech Support over the last 10 years has been infrequent but excellent on my few issues. So, if a Dell Precision Computer (business line) fits your needs, odds are you will be happy all around with the hardware and service. (I currently have 5 Precision Line computers in my home network... one of them a notebook... all is and has been runing "smooth as a gravy sandwich".) I'm not a fanboi of anything or anybody... and I'm not touting Dell... just stating the facts of my personal experience.
