There is a pretty good selection of hi-tech news channels, including CNet, ZDnet, the New York Times, San Jose Mercury and Wall Street Journal, InfoWorld to Go, and the Industry Standard, among others. I tried it out myself with an HP CE computer. It takes a while to download all this information to your palm-top, but if you aren't in a rush you can then examine the stuff on the commuter train or whenever you have a free moment. When I spoke to many media mavens who were early adopters of the technology, I found a general trend toward using an array of various technologies to stay informed. You need to use more than one method to stay up to date on current events, as well as be able to delve into the details.
Email is still the best technology for delivering quick updates.
And the web is still the best mechanism to dig in and wander around to collect lots of information. The AvantGo application sits squarely in between. A few times the information didn't download properly, for whatever reason. One channel, the ZDNN Comdex site, is completely down, should you wish to relive those glorious Vegas moments last month. The Times inserts an empty page at the beginning of its channel, making it one more pen tap away from the real data.
