Torch Mobile has released an updated version of its Iris mobile web browser. This browser is similar to Opera Mobile and Skyfire and allows you to view full web pages and easily zoom in and out. I've run into a few "out of memory" errors on my Windows Mobile XV6800 while using Iris, so it's not optimized for devices that have limited amounts of internal RAM. I'm sure you won't have any problems if you have a newer PDA smartphone that's faster and more equipped than my old device.
As mobile browsers become more powerful, I often wonder how medical students and residents will use their smartphones in the hospital setting. If they can literally access any website in its entirety, then this opens up tremendous educational resources. I think that's probably one of the biggest reasons why the iPhone has been so popular among medical students and residents. Speaking of the iPhone, Apple just announced the updated iPhone OS 3.0 and it seems silly that you still can't multi-task on the iPhone. It reminds me of the old Palm OS.
