Dell Inspiron 11z

Dell's CULV offering that we're reviewing today is the Inspiron 11z. One of the nice features of any Dell laptop is that you can customize the parts to a higher degree than most other laptops. The system we received includes an SU4100 CPU with a single 2GB DDR2-667 SO-DIMM. What's that, a single SO-DIMM? Yes, that's correct: Dell limit's the 11z to a single memory chip, with support for up to 4GB. The bigger issue isn't the single-channel interface so much as the pricing. With a single SO-DIMM the 11z is going to be slightly slower than the Acer AS1810T, and it's also going to be more expensive if you choose to go with a 4GB SO-DIMM.

Most of the other features of the 11z we received are the same as other CULV laptops: GS45 chipset with GMA 4500MHD graphics, 250GB 5400RPM HDD, and an 11.6" 1366x768 LCD. The 11z includes the standard three USB ports, flash memory reader, headphone/microphone jacks, Ethernet, WiFi, and an HDMI output. Unlike some of the other options, there's no VGA port. Like so many laptops we've looked at recently, the Inspiron 11z comes with glossy plastic surfaces and a glossy LCD. The keyboard and the plastic surrounding the keyboard are matte plastic, and we wish Dell would have simply extended that to the rest of the chassis. I have a friend with an Inspiron from a few years back, and frankly the matte plastic chassis and LCD still look better than most current laptops. Want an anti-glare laptop from Dell? You'll need to go with their business Vostro or Latitude lines. On the bright side, the light blue chassis Dell shipped us masks fingerprints and smudges a lot better than darker laptops.

We talked with one manufacturer (not Dell), and their take was that when the first glossy laptops came out, they were different from the matte options and everyone raved about them. Like so many things in life, it wasn't enough for other companies to start offering a few glossy laptops; they had to go all the way and start shipping everything glossy. While glossy laptops look nice in pictures (when staged properly), they just don't weather regular use well. Fingerprints and scratches are very visible, and it's time for a shift back towards matte designs in our opinion. We don't need to get rid of all glossy laptops, mind you; we just want more variety.

As far as build quality goes, the Inspiron 11z is reasonable. You can twist the LCD/cover a bit, but the design as a whole feels plenty durable. The keyboard is definitely one of the better aspects, though here personal preference will play a role. Dell uses flat keys that are nearly full size (with a few exceptions), and the layout works well. It's a little odd that Dell defaults to having the function keys act as special keys (e.g. adjust brightness, volume control, etc.) but you can change the default setting in the BIOS. The difference in keyboard layout and design seems very small compared to the Acer 1810, but the keys don't feel mushy and the spacing and contour of the keys felt better.

While there's plenty to like with the 11z, there is one area that I absolutely can't come to grips with: the touchpad... specifically the integration of the left and right mouse buttons in the corners. I tend to use two hands on touchpads, my left for the buttons and my right for pointing, and with multi-touch I end up with an epic fail on the 11z. Any time I want to click and drag, I usually get "zoom" behavior instead. The large touchpad seems nice but in practice either the drivers or hardware don't work well, so we recommend Dell ditch the button integration. I did try disabling multi-touch to see if that would help, and things were better but ultimately separate buttons would be superior - even without multi-touch, if one finger is on a button there are still plenty of times when using the another finger doesn't work properly. We talked to Dell about this and they are aware of the problems with the current design; it sounds as though the next Inspiron models will go back to a traditional touchpad.

Another complaint for the 11z is that the larger 6-cell battery juts out the bottom (the 3-cell doesn't do this, but you lose roughly half of your potential battery life). It's not the end of the world, but it would be nicer to have a laptop that will lie flat. Finally, the single SO-DIMM slot for memory was a poor choice; you can get 4GB RAM, sure, but it will cost more than 2x2GB on the competition, and we would have preferred DDR3 memory - lower power and better battery life relative to DDR2. Both the use of DDR2 and the single SO-DIMM slot appear to be more of a manufacturing cost consideration as opposed to features that would make a laptop better.

Ultimately, it's going to come down to pricing for most people. Well, pricing and the touchpad. The base configuration of the 11z starts at just $400, but it includes a single core Celeron 743, 2GB RAM, and Vista Home Basic, along with a 3-cell battery. In short, it's not at all impressive. With a moderate configuration (SU4100 CPU, Win7 Home Premium, 2GB RAM, 6-cell battery, and 250GB HDD) the Inspiron 11z will sell for $549 - or $589 with a non-black finish. You can customize other areas as well, and the Design Studio is a nice extra as well for another $45, assuming you want to personalize your laptop a bit. However, if you add in 4GB RAM (an extra $120 charge) the price becomes too high relative to the competition. We put together an Inspiron 11z that roughly matches the Acer 1810TZ with 4GB DDR2, 320GB HDD, and 802.11n WiFi for a total price of $694. For $580, the 1810TZ is the easy choice, and even if price were the same we'd take the Acer design if only because the touchpad was such an issue. Ideally, we'd like the Dell 11z keyboard and palm rest with the 1810T chassis, but while the 1810 keyboard wasn't quite as good it was at least "good enough" - something we can't say of the 11z touchpad.

    There's not a ton of flex - nowhere near as bad as some older MSI laptops, for example - but it does have a bit of spring and it's a "soft touch" keyboard, which just feels mushy to me. I prefer a bit more click, and the spacing and shape of the keys on the 1810 wasn't as nice as the 11z. But, that's a lot of personal preference so if you like the 1810 keyboard there's nothing else I'd complain about with the design. Reply

    Maybe it is just me, but the graphs would be a lot clear if the processors were listed out.

    I assume the power draw graphs at the end of the battery page is based on the run time and battery capacity?
  • JarredWalton - Thursday, February 04, 2010 - link

    Power graphs are based on power draw from the outlet, at 100nits LCD brightness, with all power saving features enabled (balanced power profile).

    Adding the CPU to each line compresses the graphs in a way I don't like. Just to quickly list the various CPUs:

    Acer AO751h = Atom Z520
    Acer AS1810T = Core 2 Duo SU7300
    ASUS 1201N = Atom 330
    ASUS 1005HA = Atom N280
    ASUS UL80Vt = SU7300 (dark gold = OCed to 1.73GHz)
    Dell Inspiron 11z = Pentium SU4100
    Dell Studio 14z = P8600
    Gateway EC5409u = Pentium SU4100
    Gateway NV58 = Pentium T4300
    Gateway NV52 = Athlon X2 QL-64
    Gigabyte M1022 = Atom N280
    HP Mini 311 = ION with Atom N280
    MSI X610 = Athlon MV-40

    The title of the article suggest this is a CULV vs Atom showdown. When I look at the graphics, I don't see this, I see a bunch of Acer vs Asus vs HP vs Dell and from what I gather, performance seems to be similar whatever brand the same CPU is sold with, so it really should show the name/speed of the CPUs in there.

    Per request, I've updated the chart colors to highlight other important systems. Atom 330 (ASUS 1201N) is orange, MSI X610 (Athlon MV-40 with HD 4330) is red, ASUS 1005PE (Atom N450 Pine Trail) is dark green, and ASUS 1005HA (Atom N280 Diamondville) is black. Hopefully that will help read the charts. Reply

    Well, thanks for trying anyways :)

    I guess my question is where a Z550 would stack up. Its safe to say it's 50% faster than the Z520, but I don't see that laptop in the performance line up.

    I'd wager that it's marginally faster than the ASUS 1005HA with less power draw (but how much less?).

    Basically, I'm trying to figure out what is the possibility of a CULV Sony X laptop in the near future ;) It may be unlikely simply due to die size..
  • JarredWalton - Thursday, February 04, 2010 - link

    I think Z550 gets paired up with the GMA 500 chipset, which is good for HD video decode but I'm not sure that it's actually worth using. I know Linux users don't like it because it's a new proprietary GPU with no driver support.

    My experience (which is limited to the Acer 751h) was that it frequently crashed; what I don't know is if that was the chipset, or just a poor sample laptop from Acer. I also know that I've heard from a few readers saying they have one that crashes all the time as well. Hopefully it's the 751h and not the chipset.

    As far as power draw, it should be about the same as the other Atom laptops - probably more than the 751h and 1005HA, given the 2.0GHz clock. Even then, look at the two N280 units (ASUS 1005HA and Gigabyte M1022) and you can see that not all netbooks are created equal. The Gigabyte seems to be a poor example of a netbook, though, with much worse battery life than the competition.

    At 2.0GHz Atom Z550 will still be much slower than any CULV, so I'd recommend sticking with CULV unless the pricing is very compelling.
  • OCedHrt - Thursday, February 04, 2010 - link

    The Z550 actually has a slightly lower (0.1) TDP than the N280. It's not the pricing that's compelling, but the form factor: 1.6 lb 11.1" 10.95"(W) x 0.55"(H) x 7.29"(D) Reply
  • KaarlisK - Friday, February 05, 2010 - link

    Power consumption should be lower - the TDP of the entire Poulsbo chipset is only 2.3W. However... the damn GMA 500 is HORRIBLY slow. Even for Aero. And Intel still hasn't (and probably won't) released WDDM1.1/DX10 drivers, even though the hardware supports it. Also, the driver doesn't support 8bpp color at all. Reply

    Best bet is probably to not run windows on this one ^^
    I really wish there was a CULV option, even a core solo would be much better.

    I saw in some forum that they got OS X running on it. *shudder*
