I was an early convert to the digital pen, the device that stores what you are writing in your day-book and uploads it to your laptop, PC, etc., via a cradle or mobile phone. I’ve recently upgraded and am again convinced it’s a real killer app. Not only does it give digital power to your handwriting and sketches/plans (the software trains itself to your writing style) but it allows you to share minutes, notes and actions you take away from meetings very quickly. Digital pen and paper technology is general cheaper than other mobile technology and is inconspicuous. If you write stuff down take the time to pilot/try one – it’s a simple cheap step to real-time collaboration. However, if you work in an organisation where knowledge is power the idea won’t catch on.
