What a joy not to need some sort of electronical clicky gadget simply to run a diary and notebook that's so easy to write, update and browse. Added to that there's plenty of immediately accessible date related information and it's flexible enough to stuff a few odd bits of paper amongst the pages that can have sticky notes added too.
I never need to plug it in, charge it up, find it's crashed or need to sync it - apart from with the missus' that is. So. "Up yours, all you phones,pads,tablets,L/tops and palms!"
