Query: Just doesn't last

I bought and have used several pieces in Calphalon's hard anodized line, including an 8 qt stock pot, a 6 qt stock pot, an everyday pan, a 12 qt pot, and a saute pan. Initially I was thrilled with them - great solid pots and pans at a great price. The ones I've had *are* well-made pans. I've used them every day for more than 10 years. That said, the hard anodized coating just hasn't lasted. I find that when I've made applesauce or tomato sauce from my garden produce, or a tomato-ey soup, a little of the hard anodized surface is etched away until the plain aluminum underneath (nice and shiny) starts to show through. Now I don't know about you, but I'd prefer to keep metals like aluminum (hard anodized or not) out of my food. When I noticed the hard anodized layer disappearing on my pots through normal use, I started moving to stainless cookware one piece at a time. Yes, it's more expensive to get heavy-duty quality, but I'm hoping I won't have to buy new cookware again in 10 years.
