Here's what I found after trying a multitude of styluses (or is it styli?) after buying an iPad 2. I wanted to use an iPad as a sketch book and the pad like it's name...and go digital rather than filling up notebook after notebook. So the perfect stylus has to feel like a pen and work well enough on the screen to give the tactile feel of drawing or writing on paper.I learned that styluses tips are of 2 main types - fuzzy fabric and rubber - with some additional quirky ones made of metal (O-Stylus).--Fabric tips:Pogo stylus- also used by Apple Geniuses - have a fabric tip that's great for typing or selecting or gaming even but not so good for writing or sketching anything more complex than a smiley face.There are other fuzzy fabric styluses out there sold by small stores - like the ones by the guy who has been advertising on all Mac forums and posting pictures of his store in competitors' item images. They claim that they have the best yet but I haven't tried those yet. And there are also sellers on etsy who have made sock styluses with capacitive fabric stretched over wooden wands which also claim to be just the thing.--Rubber tips:The Targus in question has a rubber tip. Please check my uploaded pic for size comparison against some other styluses.The rubber tip on this stylus looks pretty thick but is still thinner than our fingers. The problem is that it does block the view when writing or sketching just like our finger. There is also another 2nd gen ACase that has tried to eliminate some of that by creating a longer stylus and a thinner and longer rubber tip but failed to deliver as the thinner tip had to be held at certain angles to write well and became more squishy and less natural.This Targus has been the best of the 4-5 styluses I tried so far (refer to the pic) overall as it is the most responsive of all and has a matte finish stem rather than ACase's smooth finish which makes it a little less slippery to hold. The iPad 2 is already so slinky, I don't want to worry about dropping the stylus too!! It performed well on Penultimate and UPad writing apps and SketchBook Express the sketching app and captured light strokes as well as the heavier strokes. The performance was a lot better than the Acase 2nd Generation Stylus Acase 2nd Generation Apple iPad / iPhone / iPod Capacitive Stylus (Jet Black) Newest Model and a shade better than the Acase 2 in 1 Stylus + Pen Acase 2 in 1 Stylus + Pen for Apple iPad 16GB, 32GB, 64GB WiFi + 3G, iPad 2, iPhone, iPod, Motorola Xoom, Samsung Galaxy, BlackBerry Playbook (Black). And don't even bother trying the really cheap ones 3 Pack of Universal Touch Screen Stylus Pen (Red + Black + Silver), they're perhaps ok for tapping on iPhone/iPod Touch but not for writing or sketching on iPad. Although some people have suggested on forums that roughing up the rubber tip of the cheap styluses with a sandpaper makes them work better.I've also heard good things about the Boxwave and Alupen but haven't tested them so I can't say if they're better than Targus.So there you have it, Targus was the winner in writing and sketching on iPad but still not the perfect stylus as it is not as responsive as I would like. I'm still looking for that perfect stylus.
