w. Re: CDPD I thik CDPD is a great service (or should I say concept). I don't know about it's the history, but now, I think it is competitively priced. The unlimited data is something like $30 / month. The problem is that there are very few devices that can use CDPD. If you had pdQ like device with CDPD when CDPD started, it would have been popular. Those AT&T phones with like 3 lines by 12 characters are very limited. I don't know how programmable they are. Also, CDPD (at least in my eyes) is a sinking ship. The handsets are analog, where air time is more expensive, even though the data is cheap. And you know it will be dumped sooner than later. Many (if not all) the applications mentioned are have one thing in common, small data size That's why I don't understand all the rush to high bandwidth. As I mentioned here earlier, 14.4K packet data is all you need for 95% of wireless data apps running on pdQ like devices. Higher bit rate is justified for people who want to use the CDMA handset as a modem for their laptops to browse the Web. You don't even need TCP/IP. Browser access can be provided by UDP. A lot of the other services can be provided by SMS. I thought TCP/IP provides some sort of error checking, while UDP does not (but my knwledge of networking is limited) BTW, what is SMS? Joe
