PocketMod

I have just discovered something awesome: PocketMod. Basically it's a custom, disposable organiser. You choose what you want in it, eg. calendars, to-do lists, plain writing space, blank guitar TAB, unit conversion charts, games like Sudoku, etc. and then you print it on an A4 sheet and fold it a certain way and it's like a little book you carry around and use to stay organised. Screw PDAs, PocketMod rules! You can create custom pages too.
