Web pages are designed to be transmitted to users in big chunks of data at thousands of bytes per second. Wireless handheld gadgets have very small screens and operate at relatively slow speeds. The illustration at right is exceptionally large, from a PDA like the Palm, for example.
Graphics take time to transmit and occupy space in the transmitted bundle.
Currently wireless data transmissions are pretty slow. What comes out the other end may be limited to a total of 1400 bytes or so. So, while this is a marvelous new technology, it does have its limits. But now is the time to do that thinking. There will be changes in the hardware and software between now and then, but now is the time to get in, make a presence, and adapt.
