Notes on broken english

I was amazed after I saw these two sets on Flickr (first, second).

After a number of projects I work on grew up to N, I started to forget why did I come to work today? :-)

So, to work on my projects and to hold all my notes. I use a special notebook with replaceable pages. I write notes for each project on new pages, after all things is done I delete this page. It is very useful.
Also I have a PocketPC with organizer there. I don’t like it it is hard to write smth. there.

Now I’m looking at NeoMem: “NeoMem allows you to store and organize all kinds of information in a cross between a word processor and database. The interface is similar to Windows Explorer, except that instead of dealing with files on a hard disk you deal with objects in a file.”

So, how do you hold your notes? How do you keep track of your projects?
