Best prepaid for data usage in Austria?

[vegemite]

I don't have a problem with ID either, I just want to spend as *little* time mucking about getting SIM cards on my holiday as possible, by being prepared, knowing where to go, what to say, what to bring and how to configure. For example I will be in Austria for only 4 or 5 days, so I don't want to spend more than an hour two getting a SIM and setting it up. Thanks for the information people, this is fantastic news. I will get one for my wife and I as I presume we can call each other cheaply as well, and that VoIP and data will work fine on this SIM. It's mostly for Google Maps, but we'll inevitably need to call taxis and the like and I'll be damned if I'm paying global roaming rates!! I was shocked to read that phone roaming is on average the third largest expense for travellers!
