With the OpneMoko Freerunner comes a stylus which you need if you want to use for example the tiny keys of the keyboard. In general the software I know of is not finger-use ready, yet. So to use a stylus is a good idea. But you have to separately carry the stylus around with you because it's not attached to the phone or has a pocket it goes into whennot in use.
Actually I stole this idea from my friend:
Get a friend to give you a guitar pick. Thanks!
Get a piece of string. I found a black shoe lace in my moms shoe drawer. Thanks, mom!
