The only appliance I would expect to last is my slow-cooker.
I dream of a good kenwood mix-master like my Mum's that will last me a lifetime but now isn't the time to buy it.
All my saucepans, crockery, cutlery etc I buy with the expectation that they will last a life-time. I tend to pay extra to get quality so that I won't need to replace it.

ETA - I buy handbags to last a lifetime too but it just occurred to me how funny I would look as an old lady toting my paddy down the street. maybe I need to rethink that.
