they are offering the MacBook clones easy to spot , they state intel atoms inside , and as far as i know apple never did fit atoms in their MacBooks
, but they are worth the money i have a mate who bought one of those intel atom "MacBooks", looks like a 1:1 copy of the MacBook , and does the job for basic tasks and a bit more and the version he got runs without problems OSX snow leopard (came preinstalled from manufacturer in china ), he bought it of ebay a couple month ago ,way cheaper then a MacBook , more powerful then a iPad2 and cheaper as that too , with the atom 455 dual core 1.6 and nvidia ion GPU , if thats what you need ?, i played a bit with it when i was visiting him in germany and it will definitely keep up with the original MacBook air 1.6, and beats it in HD content due to the nvidia ion , but way cheaper then even a used crumbled MacBook air , he payed euros 170 for it brandnew in box from china just befor christmas , and yes it is still working , and why not the quality is not worse then what you get elsewere from dell, hp , asus , sony and the lot , and for under euros 200 , you cant go wrong , for basic computing and some HD movies
but i dont know if that site is really shipping it after you payed , better get that sort of stuff of ebay , at least then you got some protection against fraud
