i, too, have problems with wider finger tips than a key, and i have tried my centra stylus. one thing that can help when you are on a browser window is to double tap the screen. that will zoom in on the screen so you can have a bigger target...wish it worked with the virtual keyboard....r3
I have long nails too and I got the Waterfield suede pouch with a pocket; bought the stylus GTMax Touch Screen Stylus Pen ( Black + Red + Sivler ) For Verizon Motorola Droid A855. Clip the stylus to the pouch and it's perfect. I also keep a small microfiber screen wipe in the pouch. adds no bulk - sits flat in my purse.
