I just got back from a German day visit and checked my balance - it seems I used 55MB of data and my balance reduced by around 7 euros - checked with a colleague, he expereinced something similar in the UK last month.
It looks like Voda IT have quietly halved the 100MB for 2 euros option.
This isn't a problem for me, as I use the 150MB/6 euros daily option most of the time whilst tapping on my laptop in hotel rooms.
