Here's a way of creating a simple page-a-day handwritten diary for the Iliad. I've attached a file called 01January.pdf. It has 31 lined pages, each of them numbered at the top. Copy this eleven times, calling the files 02February.pdf, 03March.pdf etc. Put all the files in a directory called Diary. Copy the directory across to the Notes directory of the Iliad, and there you have it! You'll have a folder on the Iliad called Diary, with a file for each month. You can load the file and write things on the pages. You can navigate to the right date using the page navigator in the pdf viewer. Obviously you have to remember how many days there are in a month, and make sure not to book appointments on 30th February

and you may want to write the days on the page tops when you make entries so you don't forget when that all important weekend is, but it works!
Can't persuade it to sync with Outlook though for some reason...
For my next trick, I'm going to reinvent the wheel...
