I'd like to write formulas and notes on my Droid X. All the styluses that I found have a thick end and don't simulate a pen, it's more like a finger. Does anyone know of any styluses with thinner or more accurate tips? Do pens from tablets like Lenovo work?
Thin styluses are usually for resistive screens, they don't work with Droid X's capacitive screen.
I have a Pogo Stylus which was originally meant for the iphone although I see they have an Android version now. It works ok, but I feel like I have to push down harder than I want to to get it to work. It is accurate, more so than my finger, however if I don't maintain enough pressure when drawing a line for example, there will be gaps in the line. I have a screen protector on and I've never tried it on the naked screen so this might be a factor. When all is said and done I don't use it very much so I can't provide a detailed review.
If you don't want to spend the money there are a number DIY capacitive tutorials that look pretty good. Some mimic the pogo design and others don't. Here are a few:
