I'm using dell since 5 year and i was always facing issue with their machine. Suddenly my wifi device stop working i try to reach their support team but they offer me to buy new laptop never resolve my issue. They told me you should buy our paid support service. They never provide me any valid solution so i can fix it my self. Also if you are on one os and you want to install another os then you should buy their new laptop according to their worst support.
