This is the Netbook Navigator NAV13X Windows 7 Ultrabook and if we're honest, we think it's a very attractive looking device. That said, we're not so sure it's going to be on sale for too long, which is a genuine shame. Despite being called an Ultrabook, it's not an Intel-sanctioned device, which won't go down well with Santa Clara's lawyers. Secondly, it's actually a netbook running a 1.86GHz dual-core Atom CPU with 2GB of RAM and a 32GB SSD, with build to-order options running to larger memory and storage. Thirdly, we're fairly sure we've seen industrial design like this before, and given the litigious nature of the company involved, we expect a metric ton of cease-and-desist notices to be delivered to Navigator's New Jersey HQ before the weekend's over. However, if it can survive the barrage of paperwork from two of the industry's biggest companies, it'll arrive very soon, setting you back a slight $500 sans OS or $600 with Windows 7 Home Premium.

Hey, who wiped the MacBook Air logo off? Nah, we're kidding -- it's a KIRF. Sure, Apple's svelte 13-incher may have a duo of USB ports and an SD card slot, but this rig adds in a 3-in-1 card reader and an odd, combo RJ45 / VGA jack (which we assume needs an adapter). For good measure, you'll also find a mini-HDMI output, although, with 3.5 hours of battery life it may prove problematic for getting through a 1080p movie marathon without nearby power. The alloy-encased lappy has a 1.86GHz Intel Atom N2800 CPU with a GMA3600 integrated GPU, 2GB of RAM, a 32GB SSD and a 13.3-inch LED display sporting a ho-hum resolution (for a 13-incher) of 1366 x 768, just like the 11-inch MacBook Air. Amazingly, this knock-off weighs merely .01 kilograms more than its real counterpart at 1.36 kgs (about three pounds), while being only 0.1 cm thicker. Giz-China expects this Ultrabook-wannabe by Shenzhen Technology Ltd to land on Chinese shelves sometime in November for about $471. Cue Apple's lawyers in 3... 2...

The secret to a great KIRF is that it represents not just a knock-off but an homage to a beloved product (at least, that's what we tell ourselves when we sit in our workshop, trying to build the first ever shanzhai Grippity). Recently spotted in the stalls of Shenzhen, the above device is reminiscent of the MacBook Air, yes, but more tellingly, the MSI X-Slim X340. This 13-inch (1366 x 768) bad boy features a 1.2GHz Intel ULV processor, 1GB of RAM, up to 250GB of HDD, WiFi and Bluetooth, an SD card slot, three (count 'em!) USB ports, and HDMI out. You can expect to spend about $350 if you ever manage to track 'er down -- or you can just say the hell with it and go back to reading Garfield Minus Garfield. Either way, we support you. Get a closer look after the break.

Our good friends at Shanzai.com have recently got their hands on what they believe to be the king of all MacBook Air KIRFs, and put it through the ringer. Expecting a laugh riot? Not so fast -- what we have here is a pretty decent netbook, apparently. Features include an Intel Atom N280, 13-inch display, good build quality, a form factor similar in size and weight to Apple's original, a real chicklet keyboard, a remote control, and I/O options rivaling the original (including an Ethernet port, two USB ports, and HDMI). Not bad for $260. But don't take our word for it -- peep the video after the break for the whole sordid tale.

Manufacturers the world over have given this one some serious thought, and they've decided that you want something that feels like a MacBook Air, looks (vaguely) like a MacBook Air, and doesn't run OS X. Available come October 22, the iiView A2 features an Intel Atom N270 1.6GHz CPU, 2GB DDR2 RAM, 320GB HDD, a 12.1-inch display, and 802.11 a/b/g/n wireless. Shipping for $399 with Windows 7, this guy will look right at home next to your award-winning collection of Air KIRFs -- and won't break the bank in the process. Hit that read link for more info.

If we've learned one thing 'round here, it's that the KIRFsters love taking on Apple. And you know, at first glance this KIRFacious take on the MacBook Air doesn't seem half bad. Of course, check it out in profile and it looks a lot more like your average netbook than it does Cupertino's ultraportable -- but at least the shanzai manufacturer in question as thrown in a few things that were neglected in the original, including: two USB ports, a removable battery, and a PCIe slot for a 3G module. That said, they also went with an 11.1-inch display (as opposed to the Air's 13-incher), which could be a good thing or not, depending on your POV. Of course, with a 1.6GH Atom processor and 1GB RAM, this thing isn't exactly a workhorse, though it's safe to assume that the price point will fall far below that of the "real deal." But don't take our word for it -- check out a couple more views of the thing after the break.
