3G is fast but it has a weakness in my eyes that is especially relevant for mobile web browsing: When browsing to a page after having been idle for a long time, the radio interface is in idle state and re-establishing a bearer takes several seconds. In practice that means one has to wait for the first page for quite some time. But there could be a simple solution for this: Most of the time when I deactivate the keylock of my mobile device I perform an online activity right afterwards such as selecting the web browser and going to a new page. So instead of waiting with the radio interface channel establishment until I select the page, the phone could already establish the radio channel when I unlock the phone. Agreed, if it does that and I do something else after deactivating the keylock such as looking up something in my device based calender, some energy and radio interface capacity is wasted. But I'd be willing to make this compromise.
