I have got one of these too. I have chosen to keep it and with the help of our resident site expert have pruned it over a period of 4 years to keep it under control, reducing it in height, taking out crossing branches and reducing height, making more of a tulip shape. I have shade near it not surprisingly, but grow lettuce, spinach and surprisingly strawberries near it and they have done well.
This year I have had tons of apples, I have had more than I can cope with, kept fellow plotholders supplied, plus the local cooking/food charity and the play centre. All from one tree! Glad I kept it. I would try and manage it rather than taking it out.
