The role of manager is to manage all the relative activity and execute each process successfully. Dell Inspiron 15R has been the most user friendly and fast laptop. I brought it before 6 years and it is still working in a very good condition. The maintenance cost is very low and Dell provided a very good quality services during insured period. They provided genuine windows operating system and free MacAfee antivirus with 36 months subscription in amount of about 40000. What else you need in a laptop?
