Here are some favorites. Protect your Palm in sporty style by getting a case for it. Both sleek and rugged styles are available for a variety of prices and from a variety of vendors. There's even a titanium Palm case from Rhinoskin. Be sure the modem you choose matches your Palm model.
Modems are available from Palm and third-party vendors.
If you've decided the stylus that came with your Palm isn't good enough for you, choose a new one. There are a variety of weights and features available. If you'd rather have a stylus that does more than write on your Palm, you may want to get one that combines a stylus with a ballpoint pen. The PGHQ stylus has a pen hidden inside and still fits in the stylus slot of a Palm III series device. These allow you to choose what writing utensil you want.
