Thanks guys. But I only want the black one. Fnac and Darty sell it, you're right.
But they don't sell it themselves, it's from their market place. The "partner sellers" are all from China. So if anything goes wrong with the phone I'll have to send it back all the way to China to get it fixed, since Asus Europe won't deal with it if it's bought from China (I've read someone complaining about that on XDA develloper forum). Plus I don't know what version they would send me (A, B or C). They don't have all the same frequency bands. In France I need the A version. But they could send me the asian version.
Even if Darty or Fanc would sell it themselves, I still prefer to buy it directly from Asus. I could talk and send it back directly to them in case of problem. Whereas Fnac and Darty could keep me waiting longer. Or their customer care could be worse than Asus'. I don't really trust third party sellers for such an expensive product. Maybe I'm too paranoid. 🙂
