Anyone know of a website which describes the differences? Are the new walkie-talkies a monthly charge too? I don't really want a cell phone, especially now that the cell phone companies are going to compile directories of the numbers to open it up to telemarketing. However, sometimes I tag along for the ride and just shop or walk in the park while a friend is at a meeting or something along those lines. They could be done in an hour or 2 or 3, they don't even know. Would a walkie-talkie system be better for something like this (rather than plan to meet at x time only to have it be a longer time)? Thanks in advance.
