1. Cleaning doesn't really change much if it's plastic or glass. 2. With proper care, I agree, they'll look new/good for many years. Plastics can too, but to a lesser degree. 3. It breaks.

4. Glassware usually costs more. 5. Knowing that I can't break the tub of food that I have in my bag just because I accidentally dropped my bag, releases me of a lot of stress and worry.

Don't get me wrong, I do agree that plastics are toxic, but when I go to the store I always look at the prices and pick the cheapest option available, I wish I had the option of just being able to take what looks nice and pay without even knowing how much I pay, but sadly I can't, _yet_, afford that.
