Notebooks only offer widescreen format, why?

I think Dells notebooks should still offer non-wide screen format, but they do not. Why is this? For many people the wide screen is considered unnecessary because many programs aren't configured to be wide. Also, it changes the weight and size of a laptop. Laptops are meant to be portable. My grandpa recently got a laptop from Dell, but he is weak, so he doesn't carry it around much, and that's what a laptops for. This is because the laptop was too big, it was wide screen. Please start offering normal laptop screens again. Many consider wide screens a waste. But keep offering them if you must. Another friend complained to me about your wide screens as well.
