After our less-than-enthusiastic review of the Dell Inspiron 11z, we decided to take a second look at this budget-priced ultraportable notebook. The "new" Inspiron 11z promises to kick things into high gear thanks to a new low-voltage dual-core processor, Windows 7 and an extended life battery. Should this updated ultraportable be on your holiday wish list? Keep reading to find out.

Build and Design
Nothing has changed about the build and design of the Dell Inspiron 11z since our original review. The 11z retains a very simple design with a solid color glossy lid, matte black chassis, and a silver painted palmrest. When closed the shell is nearly flat, with few items sticking out the bottom cover, making it easy to slide into a slipcase or backpack. Inside the 11z keeps things equally simple with just the touchpad, keyboard, power button, and power indicator light. There are no media buttons outside of function keys on the keyboard, and there arent even activity lights or touchpad buttons. Dell wanted the design of the 11z to be as simple and straightforward as possible ... and they succeeded in making this netbook clean and easy to use.
Our new review unit of the Inspiron 11z includes a "Jade Green" lid which looks a bit more like light lime green to my eyes. The paint quality is quite good, but Im not crazy about the fact that Dell charges $40 for any color choice other than black. Sure, Dell deserves to make some money on customized options, but an extra $40 for a plastic lid that is painted something other than black seems excessive. Build quality is average with a mix of a firm support structure and flexible plastic exterior. The chassis feels reasonably durable thanks to strong internal support under most surfaces. The palmrest and keyboard showed very few signs of flex under strong pressure, but the area just above the keyboard does suffer from a little bit of loose fitting plastics when pressed. Additionally, the slightest bit of pressure will cause the scree lid to bend and flex, but the paint seems relatively scratch resistant.
Internally the design of the 11z is very friendly for users wanting to upgrade or replace components. At first you might notice there is no bottom access to components. Instead, Dell put all user-accessible components underneath the keyboard (which can be removed by taking out three screws). With the keyboard off you have access to an open WWAN slot, the system memory, hard drive, and heatsink assembly. The WWAN slot was functional, recognizing the Verizon card borrowed from a Dell Latitude D630; but it lacks antennas to allow the card to send and receive data. Dell currently doesnt offer the Inspiron 11z with broadband wireless access here in the US.
Screen and Speakers
The 11.6" screen on the 11z is a nice step up from the typical 1024x600 netbook screens. The 720p HD resolution of 1366x768 gives you the same resolution as most mainstream full-size notebooks. This means that menus and other items that need more vertical space are no longer a problem. The panel offers good color saturation and the LED-backlighting frovides even coverage and helps extend battery life. Contrast is average, and varied depending on the vertical viewing angle. The vertical viewing sweet spot is quite small, meaning colors quickly look washed out when you view the screen from above and look distorted or inverted when viewed from below. On the bright side, horizontal viewing angles are quite good ... making it easy to share online videos with someone seated next to you.
The speakers sound slightly better than the average netbook speakers. The speakers still dont provide much bass, but you can hear some of the lower tones and some solid midrange. Maximum volume levels are loud enough to fill a small room when watching a movie or listening to music. That said, if you want to enjoy movies in a group setting then you should use the laptops HDMI port and connect it to an HDTV. The HDMI cable passes both video and digital audio to your home theater system ... and even the worst HDTV speakers will sound better than most notebook speakers.
Keyboard and Touchpad
The keyboard on the 11z is basically full-size and very comfortable to type on. The layout is easy to follow, taking no time at all to transition to and start typing at full speed. The key design is flat, similar to Chiclet style keyboards, but without an inner bezel dividing the keys. Individual key action is smooth, giving off a soft click when pressed. One odd feature Dell has been transitioning to on newer models is the reversed function key layout. If you want to adjust brightness, you press the correct button and the brightness changes. To hit F5 to refresh a page, you now need to hit FN+F5. Thankfully this feature can be disabled for more advanced users.
If you read our first review of the Dell Inspiron 11z then you know we didnt like the touchpad. In fact, we went as far as to call the touchpad on the 11z the worst touchpad ever. Well, the touchpad on our new review unit of the 11z uses the same ELAN touchpad hardware, but this time Dell has updated the drivers for better performance. This makes the touchpad a little more usable, but it still suffers from many of the same problems.
If you hold one finger on the touchpad over the left or right button and try to move around the screen a few things might happen. One of the most common problems is unwanted zooming, meaning you will change the size of icons on the desktop or the size of text when viewing documents or webpages. We also still noticed the speed of the X and Y axis input isnt consistent. Moving your finger side to side makes the cursor move more than if you travel the same distance up and down. A simple test is drawing a circle on the screen with your finger, where the 11z makes wide ovals instead.
Bottom line, we still consider an external mouse to be a must-have accessory with this notebook. Considering that "laptops" are designed to be mobile computing solutions its extremely frustrating that the touchpad on the 11z cant get the job done.
Ports and Features
Port selection is average for most netbooks, with the exception of HDMI in place of an older VGA port. Dell included three USB ports, audio jacks, an SDHC-card slot, and LAN connector. Users might also notice that Dell went with a full-size power connection on the 11z, the same shared with every other Dell notebook. The power adapter is another change over most netbooks, as Dell included a 65w thin power brick with this model. On one hand it is nice to get a high quality power adapter that will probably hold up better over time than most netbooks adapters, but on the flip side it is pretty big.

erformance and Benchmarks
We werent very impressed with the Celeron 723 processor in our first review unit of the Inspiron 11z, but we had much higher hopes for the new low-voltage Pentium dual-core SU4100 processor. The new dual-core processor offers twice the cores and twice the cache as the Celeron 723 processor ... and the synthetic benchmarks confirm the new CPU is much faster. The Intel X4500 integrated graphics even saw a slight improvement thanks to the new CPU and Windows 7. Although the 11z still doesnt offer quite the same performance as a mainstream notebook, this is much better than a typical Atom-powered netbook.
In our HD video tests the 11z is able to play all of our video trailers. The 480p and 720p videos plays with no problems at all, and after some minor tweaking the 1080p trailer plays smoothly. Playing 1080p video puts it above other netbooks we have tested, but in the real world most users wont be watching 1080p video on a netbook that only offers a 720p display.

Heat and Noise
Temperatures stayed within "lap friendly" levels during normal use with the 11z. Temperatures did spike during our synthetic benchmark tests, but the highest temperatures were centralized around the heat exhaust outlet, and most users wont be stressing the system at 100 percent capacity very often. Noise levels from the heatsink fan are minimal even when the fan is on the "high" setting. Our previous review unit made a high pitch whine when it was fully turned on or in its sleep mode, but this review unit of the 11z had no such problem.
The external temperature readings shown below are listed in degrees Fahrenheit:
Battery Life
This review unit of the Inspiron 11z includes a high-capacity 6-cell Lithium-Ion battery rated at 56Wh. In our test with the screen brightness set to 70%, Windows 7 set to the "Dell" propietary balanced power profile, and wireless active the 11z stayed on for 4 hours and 7 minutes. This isnt too impressive considering that the standard 28Wh battery delivered more than 3 and a half hours of battery life with a single-core processor in our first review of the 11z.
Conclusion
The Dell Inspiron 11z remains a capable alternative to a traditional netbook that suffers from a few frustrating problems. The new low-voltage Pentium dual core CPU delivers good performance when paired with the Intel X4500 integrated graphics. Likewise, the fully-functional HDMI connection makes this ultraportable notebook attractive to people who want to connect their laptop to their HDTV. Unfortunately, the praise pretty much stops there.
Although the extended life battery gave us more than 4 hours of battery life in our lab tests, that isnt as impressive as what weve seen from other ultraportable notebooks and netbooks. The touchpad remains the weakest link in the technological chain for this notebook, as an external mouse should never be a requirement for a "laptop." Additionally, while the starting price of $399 is very compelling for the holiday season, the cost of the Inspiron 11z quickly skyrockets to more than $600 when you configure a higher performance system.
Bottom line, the Inspiron 11z offers a great form factor and solid performance for a travel laptop, but average battery life, a troublesome touchpad, and pricey upgrades prevent us from calling this one a winner.
Pros:
* OK performance as configured
* HDMI out for HDTV connection
* Perfect size for a travel laptop
Cons:
* Touchpad still problematic
* Average battery life
* High price as configured
