For one thing, Visor has been able to take advantage of its more flexible interface allow users to select options by clicking with a stylus from its larger screen rather than having to select options from the limited of number of button available on a cell phone. You can, for example, put someone on hold or initiate a conference call by selecting the options from a menu. Most mobile phones also offer those features but knowing how to implement them can be quite tricky. Despite some obvious advantages, the phone has some drawbacks. For one thing, it is harder to use in a moving car or in a dimly lit room because most its functions are controlled by clicking on the screen with a stylus.
Some people can dial a standard cell phone without even looking at the keypad.
That would be nearly impossible with the VisorPhone. Another obvious drawback is that it's bigger than most phones and, when it's plugged in, it makes the Visor a bit bigger and heavier. Also, if you have other Springboard modules for the visor, you have to remove them to plug in the phone. Although the phone has a built-in modem, it is not being marketed as a web surfing device like the Palm VII or a Palm V with the Omnisky wireless snap on modem. A Handspring spokesperson told me that the company doesn't believe that the experience of surfing the web on a device like this will be all that satisfactory for users and that company has decided not to promote it for that use.
