If You Write in a Foreign Language: Some of our friends who text or email in language other than English find a stylus essential. Especially when it comes to writing characters, you can write faster and more legibly with a stylus. One of our friends had a keychain on her phone with a small stylus conveniently attached for writing messages in Japanese. If Your Smartphone Has a Huge Screen: If you're an owner of one of the Samsung Galaxy Note/Note II models, a stylus seems to come in handy because the phone's screen is in that sweet spot between a standard smartphone and a tablet. Especially for gaming, sometimes it's a bit easier to use a stylus than your finger for games like Draw Something or even match 3 games. If You Live in a Cold Climate Area: Unless you want to buy a pair of touchscreen friendly gloves, another solution for accessing your phone or tablet in the cold is with a stylus. If You Like to Draw: As I mentioned before, for games like Draw Something, you can achieve a lot more accuracy with a stylus. If you're an artist and like to use your smartphone or table to doodle, it definitely lets you get more detailed versus using your finger.
A couple styluses that I'd consider if I were to purchase one would be the Pogo Stylus, Bamboo Stylus Pocket and this fun Crayon-shaped stylus.
