Voice is clearly such a good solution that almost any other method seems like a clunky evolutionary step. Voice technology will probably still take a while to develop and reach the level of maturity that most of us will expect of it. Even so, it is highly likely that it will integrate relatively easily into an existing Web numbering system once it's viable. Others remain at least a little sceptical about how much easier it makes a consumer's life when they have to think of the wireless Internet in a numeric way. Most though consider numbering a fairly intuitive idea and a natural extension to have numbers versus letters.
Many people memorise multiple digit phone numbers with ease.
It is important to note that these Web numbering schemes do not attempt to address the other issues that have limited the appeal of accessing the Web from a cell phone. Such issues as the relatively small percentage of callers who have Web-enabled phones, cumbersome data entry by keypad, and Web sites that have been slow to reformat their content to be readable on tiny cell phone screens, still need to be addressed in their own right. Web numbering is simply attempting to speed navigation on the wireless Web. You might say Web numbering is a whole lot more about quickness, not so much about stickiness. A numeric address will simply make it quicker.
