Tongues have been wagging about a potential Mac netbook for some time now, so it's not exactly surprising to see an obscure Russian source post purported images and specifications of such a system. 9to5Mac has posted the goods right here, although even it points out that the image is likely a mockup done in Photoshop.
Nevertheless, the photo and specs seem strangely believable. The netbook itself looks like a cross between a MacBook Air and an aluminum MacBook, and the Russian source quotes a launch price of $899—pretty much what one might expect an Apple netbook to cost. (Hey, after all, that's exactly what Sony charges for its stylish Vaio P.)
On the hardware side of things, this "MacBook mini" is said to have a 10.4" 1280x768 display, a 1.83GHz Intel Atom processor, an Nvidia GeForce 9400 integrated graphics chipset, 2GB of DDR3 RAM, a 64GB solid-state drive, 802.11n Wi-Fi, and a 5100mAH battery. Aside from the arguably anemic processor, that certainly seems like the kind of netbook Apple would introduce. And according to Google Translate, the Russian source quotes a spring 2009 ("весна 2009") launch time frame.
