If you're looking for halfway decent drawing stylus, you might want to consider this one. I use it on my Amazon Fire and it's not bad. Better than those fat, kinda clumsy, squishy-ended ones. Really, the only problem is that if your stylus sees a lot of miles, you'll have to replace the nibs semi-often.
looks pretty good to me. Im trying to decide if sketching on an ipad is better than a sketchbook when out and about. Ipad has nicer results and doesnt clog the bag up but its also far more expensive if it gets stolen or lost XD
