Surfing the mobile web at a fair price

Link: m-trends.org: Open Letter To Vodafone.

I think there is something completely wrong going on here… For my work and research I surf (connect) the mobile web at a minimum average rate of 10 times a day at 0,50 Euro/day, resulting in an excessive 150 Euro/month extra added to my bill just to surf the mobile web (!)

Let me ask you, do you really think this a fair price for being able to surf the web anytime anywhere?
