I'm the same, I plan on purchasing an LV agenda PM later this month, (trying to decide between Bronze vernis or Rouge Fauviste), I tried to use my iPhone last year as my agenda, massive fail!
I'm a visual person and I need a 'week over two pages' view, I can't cope with day to day.
i stupidly instead of buying 2012 refills i bought a larger kate spade paper spiral agenda and i barely use it cuz its so big and annoying -.- im just so scared to use my vernis agenda i dont want to damage it.
