ProSupport isn't just excellent warranty coverage, often adding Plus (accidental damage) is not expensive either. Laptop literally run over by a car? Dell fixes or replaces it.

There are funny aspects too, we had a laptop with a broken rubber handle and Dell didn't have the available part, or replacement laptops of the same model, so they gave us an equivalent system a three years newer model.

At the desktop tier Dell Command Update is probably just the best driver/firmware update tool for a business.

Their server side can be a harder sell, it's a lot pricier than competitors sometimes without a ton of justifiable benefit for choosing them.
