The green Eee wasn’t supposed to be available until early next year and it was supposed to be the 2-gigabyte version. Well there’s apparently a 4-gigabyte version shipping out of Taiwan that’s only being offered by two Taiwanese sellers on eBay’s German site. Weird.
Both sellers appear to be established enough (one’s got a 417 rating, the other is 2260) that they wouldn’t be fly-by-night operations, so this could very well be legit. There aren’t any actual photos of the green models aside from ASUS promotional photos, so please proceed at your own risk and remember not to talk to strangers.
