etienne66, no VISA does not cover if you don't like it. Ten again they didn't when I bought my Atom Phones from Hongkong either, and even though the Life wasn't all I wanted it to be it got better with a bit of help from XDA Developers. It's basically a leap of faith - if you think you can deal with it and be patient until it's hacked if you don't like the standard OS (took all of a week after the Nook Color came out...) then you buy it. And you'll be one of the first who has it. If not you read reviews and make an informed deciscion, but the problem is that even if tech journalists hate it you may love it and vice versa. Take me. I hate Apple's OS for computers, and still tech journalists rather uniformly says that it's the bee's knees and so on. And they hate Windows Mobile 6.5, which I happen to love (again with a bit of help from XDA Developers). I won't trade my HTC HD2 Energy Max Sense for any iCrap or Android phone (not because I hate Android (yes, I do hate iCrap...), but because I have a lot of applications that won't run on Android (or even Windows Phone 7)).
As for the VISA fraud alarm I haven't had any. No problems here, but I guess that's because I deal with Norwegian VISA. And I'm guessing that your VISA are about as paranoid as the TSA...which in my book would make them certifiably insane! I much prefer the Texas way (been to San Antonio several times): Be polite until they're not polite to you, then you kick their butt!
Got the confirmation on the preorder from Notion Ink as well now. They will send me a 900 because I live in Europe, and a correct power plug for my style. Everything is based on where you order from. Smart move!
