kou - I love my piccolo, although I managed to get mine in the sale, they are quite dear. Sorry to lower the tone a bit, but they are also the perfect size for a spare Tampax, very discreet.
You mentioned your electronic thingy rather than a diary. Perhaps one of the zipped agendas, or card case etc might be perfect for it, you'd have a fun time finding the perfect size, you and your SA might have to be a bit inventive. I remember someone else mentioning a particular Hermes leather item that fitted their pda perfectly, can't remember which thread.
