Data roaming costs are just crazy. It can easily cost €13/mb while abroad. And, just the front page of the Irish times weighs in around a megabyte. You could buy a car for the cost it would take to download a CD. I have an HTC TyTyn and use a utility called GPRS Monitor which switches off the data use when I'm roaming. It also monitors my local usage and can warn if I'm getting close to using up my quota. Might be worth looking to see if anything like that is available for your phone.
