A few weeks ago I was wondering if it exist a tool for PDA that woud be usefull for webmasters. I think I've found such tool.
It's a tool that record your handwritten notes on your PDA or on your PC, either via IrDA or USB connection.
You can quicly draw the structure of the website, draw the page layout, organise your notes in categories, send them by email,...
The data are stored in "ink files" and can be exported to .JPG that can be used as a background in dreamweaver so you can draw your tables/css box/frames on top of your handmade design. You may also grab the vectors by printing to a PDF Writer virtual printer and the reimport your notes/drawings in a true drawing software.
