Stylus Recommendation

We were all high school students, and not all of us were EE. So your opinion
counts, and yes I read it. I spent a good deal of time today fiddling with
different stylus ideas. ON one hand we do not want to burden the design (
The ID or the software ) with a requirement to use a stylus. On the other
hand, we cannot stop people from writing software that works better with a
stylus. So, How to balance these two. Some of the ideas on the list have
given me some thoughts. I'll share them with the Industrial design guys.
Good ideas can come from anywhere. From the High school student to old
guys who has done this for years. So, as an exercise, look through the list.
Collect the ideas. List there pros and cons. See what you come up with.
draw some pictures. If we had a monopoly on good ideas we would not be open


And you just gave me a great idea!

       I am not an electrical engineer either (I'm a highschool student) 
and I think that it's more important to get the phone ready than 
problems like "where the stylus will be attached?". In the end the 
freerunner will be a developer and not an end user phone. Besides I 
don't know how much the OpenMoko team is considering our suggestions (no
