I know, there’s not a lot of room in the world for the stylus any more. Resistive touchscreens are on the way out, right? True, but tell that to the 766,500 Nintendo DSes sold last month. So there’s a bit of a market. Personally, I find the DS’s stock stylus a bit short — so a little extra length would be good, and I wouldn’t mind having my initials in gangster letters on it either.
For just under $10, you can get a themed stylus in either metal or the white, slightly flexible plastic they use for some stuff over at Shapeways. I’d definitely get the shield, although the mushroom is pretty cute. I doubt these will fit in the DS’s little stylus slot, though.
