I put together a table in MS works of all the pipes I have, witha picture and a notation. Unfortunately, MS Works sucks, so it doesnt transfer well to other's computers. I keep a tobacco diary in MS Word too. AND if you have an IPAD, one can put Dropbox on the iPad and the Computer (or on a laptop if you prefer), and keep the Word document in the Dropbox file for access wherever you are! I use Quickoffice Pro on my iPad, which opens MS Word and Excel documents for editing. Dropbox wont let you edit the things.
I want to eventually transfer my Pipe log onto an Excel format so I can open it on my iPad as well.
I confess, I tried to do a spreadsheet to keep up with my pipe maintenance, but it was a bit too overwhelming.
