I use a stylus with my iPad. I draw with it, write with it, and it keeps my screen cleaner. I am always on the lookout for a better stylus, but simply doing more (with a higher price tag) isn’t what I consider to be a great stylus. I have used expensive ones and cheap ones, with my current stylus being a relatively inexpensive workhorse from Griffin that works well and moves smoothly across the screen. It’s a good stylus.
The only draw back that I consider worth paying to overcome is sensitivity. A cheap stylus doesn’t do anything with pressure and so it is difficult to get the perfect ‘light’ brush stroke. Some apps use speed to adjust the stroke but that changes the whole way you draw. That’s why a release from Wacom (I have one of their stylus kits for my desktop from a few years ago) has caught my attention.
