They do seem to be dashed useful instruments. Lexi started listing all the things one could do with them and I'm sure she would have gone on for hours if I hadn't stopped her. So far, however, I've been happily sticking to the moving pictures and typing these telegram message whatsits to you all. I shall leave most of that other stuff to brainy persons like your good self, madam!
I shall certainly have to biff off to that cafe you mention, thank you very much for the advice!
