I am disappointed with the mobile options, too. However, I don't find channel3000.com that slow. I like that the content is on the left and ads on the right. The small size of my screen eliminates the need to look at the ads. NBC15 has the opposite layout so I see ads, not content. I have to scroll for the content.
UW Space Science and Engineering has a nice weather site made for PDAs. It's web site is http://www.ssec.wisc.edu/data/paw/
I broke my old phone about a month ago. It was a Palm Treo 650 without wi-fi not 3G service. I had dropped it so many times, but this last drop was fatal. I upgraded to a Windows Mobile 6 with both a wi-fi card and 3G service. Viewing web sites has greatly improved.
