I do for travel for work about 200 - 300 km a day, I'll use blackberry traffic or google maps, also check twitter, my email, browse CB also pull up the odd youtube video while waiting on the road.
When I first got my data plan a few years back my provider had given me Unlimited data plan for the first 2 months for the price of 500MB just so I could see my usage. Maybe something you could try to get out of your provider.
