Netbook Navigator created a laptop called the Nav13X that has Ultrabook looks with a netbook processor.
As you can see, the Nav13X looks a lot like a MacBook Air or an ASUS Zenbook . It has a 13-inch screen with the typical screen resolution of 1366 x 768. However, instead of sporting an Intel Core i3, i5, or i7 processor, the Nav13X has a 1.68 GHz Intel Atom N2800, the latest Cedar-Trail based processor. It also can be configured with 2 or 4 GB of RAM, an SSD with 32, 64, or 128 GB of storage, and your choice of Windows 7 (Home Premium, Professional or Ultimate). For peripherals, the Nav13X has 2 USB 2.0 ports, a mini-HDMI port, and an SD card slot.
While the Nav13X starts at a reasonable $499, that is for a machine that has no pre-installed OS, only a 32 GB SSD, and 2 GB of RAM. If the SSD were upped to something more reasonable, like 128 GB, starting price is $899, still kind of steep for something that is more netbook than Ultrabook in specs.
For a model that has moderate specs that mirror typical Ultrabook offerings — 4 GB RAM, 128 GB SSD, Windows 7 Home Premium installed — the starting price is more around $1099. For less than or around that same price, you could get several other actual Ultrabooks with Intel Core i5 processors.
So while on the face of it, it seems like a good deal, I would strongly suggest at least looking for deals on “real” Ultrabooks before considering the Nav13X.
