MobilePen has joined the likes of Motorola by releasing a third-party add-on for Symbian or Windows Mobile-powered smart phones. It features two options for quick and easy text entry: keyboard for touch typing, and handwriting recognition for English or Chinese. This device can also connect to your PC to operate as a miniature tablet. It weighs just under 2 ounces and measures 3.8 inches by 2.3 inches by .4 inches and should be available in China soon for around $430. For that price you could just upgrade to a phone that has a keyboard.
