If your thumb muscles are sore from editing documents or sending lengthy e-mails on your PDA, relief is on the way. Thanks to Bluetooth technology (ak.a. “wireless”), you can now get a special full-sized keyboard that will work with your Smartphone or PDA. Just set your phone in the attached PDA stand and… viola…you have an instant office. There’s no PC needed, either. Just download the software right to your phone. Wondering how or why you’d lug around a big keyboard for your miniphone? They thought of that too. Weighing in around 6oz and folding to the size of a cup of coffee, these keyboards come with a small carrying case. With many manufacturers now on the PDA keyboard bandwagon, you can get your hands on one online for under $80 through almost any technology reseller.
