It looks like Pocket Express is about to be released. I have downloaded the trial version and its great. Here are my pros and cons. Pros:
1. Speed. This is much faster than a wireless browser.
2. Content. News, Weather, Sports, Maps, etc.
3. Size. Only 10% the size of similar wireless content. Cons:
1. I cannot customize the sources. For example, all of the news sources appear to be Reuters.
2. Price. $6.99/month or 69.99/year
