The real question you have to ask yourself is "what do I need the access for?"
If you just surf the web on the phone and you don't have high speed internet (which I do not have) you will feel like 1996 dialup user all over again.
The web is only ONE of many connected products/services. Check your plan to make sure that airtime/webtime/internet are all included in your data plan so that when you check email (which is the most functional feature for me) or use google maps (second on the list for me) that there aren't any extra charges for that data access.
Again, the only other app I've used is online Poker, that I never use because there aren't enough other people using it to have any fun playing with other players. Man, this GTD thing has got to get to some poker players.
