I use it to take notes on Windows RT Surface tablet with the application Bamboo Paper. It is not as responsive as a real pen on paper but the result is quite interesting. The width of the peak was quite annoying at first but you get done quickly and embarrassment disappear.
The stylus itself is very light but still robust and very well finished. The tip is replaceable no need to throw it away when it is damaged.
I already had the first version of Bamboo Stylus. It is heavier than this one but made the writing is virtually identical.
