which aspect was not fit for purpose?
Oooh, I would have loved to have a stab at that one but I'm going on holiday tomorrow and I just don't have time to write 2-sides-worth-of-A4-paper in reply to your question. Will have to wait a fortnight (no interweb where I'm going..) before settling in with a large bag of popcorn to see what people write on the subject.
