Yeah, regional restrictions are a mess. I went in Denmark for a while, and had steam going "Hey, what do you think you're doing, using a French credit card and you're in Denmark ??"
Well, that's the first time i've seen steam support being effective.
Then it sometimes happens to be a good thing. I tried to buy trackmania , so i didn't need the cd anymore. Steam fails, my being still in denemark i give up. The very next day, Hilys showed up "Hey guys, we're going to do an update with a no-cd".
I bought my fist epub. Now i need to un-drm it. And calibre will do the rest.
And wooo, a properly formated ebook
