Introducing the HP dm1z
HP's been on board AMD's ultraportable bandwagon since the chipmaker first shipped the underwhelming Congo platform, and HP continued to produce reasonably compelling not-quite-netbooks with the Athlon/Turion II Neo-equipped Nile platform. But now that AMD has made a concerted effort to dethrone Intel's Atom with Brazos, HP has been able to produce a true netbook competitor. We have the shiny new dm1z equipped with the AMD E-350 in our hands: is this the netbook we've been waiting for?
HP has refreshed their dm1 line with AMD's Fusion APUs, but what else does their shiny new netbook bring to the table?

The most interesting thing about the HP dm1z, right off the bat, is that it's the first netbook we've reviewed to feature AMD's Fusion APU, and HP equips the dm1z standard with the most powerful one in the lineup. The AMD E-350 comes with dual 1.6GHz Bobcat cores, 1MB of L2 cache (no L3), along with a Radeon HD 6310 GPU integrated into the processor die. The HD 6310 is more or less an on-die Radeon HD 5450, with 80 DirectX 11-class stream processors in AMD's VLIW5 configuration and clocked at 500MHz.
The E-350 features a single 64-bit DDR3 memory channel capable of supporting up to two DIMMs for a total of 8GB of RAM. The whole shebang has a TDP rated at 18 watts, which may seem like a lot until you remember the IGP is built into the processor instead of the Northbridge, and instead of having a Northbridge+Southbridge combo as is traditional for AMD, the E-350 requires only the Hudson FCH, a tiny chip that includes just enough SATA, USB, and PCI Express connectivity to get by. Besides, TDP isn't the same thing as actual power requirements—18W looks to be close to the maximum the APU can draw.
Given the small form factor of the dm1z and its intended market, HP is actually fairly generous in its stock configuration. At the time of writing, HP offers a "free upgrade" from the base 2GB of DDR3 and 250GB 7200RPM hard drive to 3GB of DDR3 and a 320GB 7200RPM hard drive; this is the configuration you're most likely to see in retail. The Western Digital Scorpio Black is pretty fast for a mechanical drive, too, so it's nice to see HP step up and offer this 7200RPM drive as standard. Connectivity is handled by Realtek Gigabit and 802.11b/g/n wireless networking along with a Bluetooth 3.0-capable Ralink chipset. About the only complaint we really have on this front is the lack of a separate microphone jack, but that's relatively small potatoes in the grand scheme of things.
The Swankiest Netbook You Ever Did See
First we should make one thing clear: the HP dm1z is basically small enough and slow enough to be considered a netbook, with most of the good and bad connotations that term brings with it. With that in mind, the dm1z is a remarkably attractive piece of kit and as you'll see, in many ways it feels like the netbook finally arriving at about the form factor and performance level it always needed to be at.
The lid of the dm1z is a textured black plastic that is a healthy stride away from the glossy plastic hell that used to plague HP's older models; it's attractive and doesn't easily pick up fingerprints and smudges, and the HP logo is nice and subdued in the lower corner. There's a silver trim that extends around the lid and into the body.
When you pop open the dm1z, you'll see that trim matched with silver matte plastics on the screen bezel and tastefully framing the keyboard and touchpad. HP has made some really great strides as of late in improving the looks of their notebooks, and the dm1z continues that trend. The silver plastic is used for the interior surface along with the battery and rim of the system and is complemented by sparse usage of white LED indicator lights.
HP has been pushing a standardized chiclet-style keyboard across all of their lines at this point, and it suits the dm1z. The 11.6" form factor allows HP to squeeze a comfortable full-sized keyboard into the unit, too, with the document navigation keys helpfully and logically mapped to Fn+arrow key combinations. The keys aren't marked that way, but it's easy enough to figure out. There's no number lock either, but I've never found the 10-key wrangled onto the main keyboard to be particularly useful. The only complaints about the keyboard are minor ones: HP, like Dell, opts to default the function keys to controls and shortcuts (though this can be toggled in the UEFI), and the left and right arrow keys are basically double-sized compared to the up and down arrows. On the whole, though, this is a solid netbook keyboard that most people should be very comfortable with.
The touchpad is more of a mixed bag, but kudos to HP for actually using a separate piece of plastic for it instead of just building the sensor into the inside panel. Of course, there's a reason for that: HP is using the same clickpad that's dogged their mainstream notebooks over the past year. To be fair the HP implementation is among the better ones used for Windows-based systems, it's multitouch capable, and the tracking surface is comfortable, but we would still rather see dedicated buttons on future refreshes. If you're using an external mouse or keep brushing the touchpad (not a problem I had in testing it), you can actually double-tap the top left corner of the touchpad with your finger to disable it; a pinpoint orange LED will glow when the touchpad is disabled.
One of my favorite features of the dm1z is actually on the bottom. HP has gone a long way towards simplifying user upgrades by simply putting one large, screwless panel on the bottom of the unit. The panel simply snaps on and off and feels both sturdy and user-friendly while also making the dm1z as a whole more attractive by hiding serial numbers and the Windows key. As you can see, everything you'd want to upgrade is easily accessible.
Taken as a whole I'll admit to being fairly smitten by the dm1z's design. It's remarkably well streamlined and clearly designed to improve the user experience while avoiding looking too chintzy or cheap. This is definitely one of the best-looking netbooks I've ever seen and it feels very solid.
