Netbooks deserve a lot of credit not only for ushering in an era of affordable ultra-mobile computing, but also for spawning a new class of small-form-factor systems dubbed nettops. These similarly inexpensive PCs are less intimidating than cobbling together a Mini-ITX rig from discrete components, and they're usually smaller and cheaper than do-it-yourself alternatives.

There are performance limitations, of course, but the low-power platforms that underpin nettops get more potent with each new generation. At the moment, AMD's Brazos platform—specifically its Zacate APU—is the cream of the crop. The chip's dual CPU cores are quick enough to handle basic desktop computing tasks, and its integrated Radeon graphics processor has formidable video decoding capabilities in addition to a healthy dose of 3D horsepower. This well-balanced attack makes Zacate ideal for home-theater PCs and lightweight desktops, so it's no surprise that we've seen numerous nettop makers get in on the action. Zotac to trot out a Zbox AD02 with a Zacate-based E-350 APU inside.
The AD02's 7.4' x 7.4' x 1.7' (188 x 188 x 44 mm) dimensions are pretty typical for a nettop, so it doesn't break any new ground. However, the same can't be said for the new Zbox Nano AD10, which is half the size, just as fast, and even better equipped. A handful of Zacate Yes, the Nano actually fits into one of my meaty mitts. The thing measures only 5' x 5' x 1.8' (127 x 127 x 44 mm), giving it a substantially smaller footprint than the old Zbox, while maintaining a similar thickness. To put things into perspective, consider that the Mac Mini has dimensions of 7.7' x 7.7' x 1.4' (197 x 197 x 36 mm).

Of course, the Mini starts at $600 and features a Core i5 CPU, so it's not really in the same class. When decked out with a 320GB hard drive and 2GB of RAM, the Nano is slated to cost just $320. That fully loaded model is known as the Zbox Nano AD10 Plus, and it doesn't include an OS. There will also be a Plus-less barebones variant sold sans hard drive and memory for just $270. The Nano's 5,400-RPM hard drive isn't nearly quick enough to take advantage of Hudson M1's 6Gbps Serial ATA controller, but one could conceivably plug a faster drive into the eSATA port at the rear. Unfortunately, the port doesn't feature integrated USB power.
That omission is particularly maddening in light of the fact that the AD10 has a mere two USB 2.0 ports; Hudson M1's circuitry allows for 14, but Zotac doesn't take advantage. At least the company was smart enough to add a couple of SuperSpeed USB 3.0 ports to the rear of the system.

There's no reason for people to be forced to endure plodding USB 2.0 transfer rates when using external storage devices. With internal storage limited to a single drive, external solutions are probably even more popular in the nettop world than they are with desktops. On the networking front, the Nano complements its Gigabit Ethernet jack with built-in Bluetooth 3.0 and 802.11n Wi-Fi. Unlike Zbox designs that feature integrated antennas, the Nano has a jack for an external one.
