I got this Latitude X1 from the Dell Outlet site. The system came out to just under $1400 before tax, good price considering the way it was spec'd out would've cost $2300 from Dell's Home or Business sites. The computer was in Brand New condition, i had a friend check the service tags history, the computer was cancelled right before it shipped out. Sorry about the crude pictures at first, better pictures of the system will be up shortly but for now, here are comparison pictures with the D410, I600m, I700m, I6000, and XPS Gen 2.

Specifications:
Intel Pentium M 1.1 ULV
1.28gb DDR2 400
60gig 4.2k HDD
Intel 2200BG
Bluetooth

Overall performance is great. The 1.1 ULV runs alot better than i expected. I'm using this mainly for school and internet but i thought i'd try a few games on it. World of warcraft runs a steady 25-35 FPS, large cities like Ironforge will drop the FPS to about 10. Also installed Counterstrike Source which played at 15-30 FPS depending on whats going on in the game. Photoshop CS2 and Autocad runs easily on the system as well.
The keyboard feels much more comfortable than the smaller 700m keyboard. The Period key is much better placed than the half keys of the 700m. One thing i dont like with the keyboard is the keys are more stiff than other dell notebooks i've used. It actually takes some getting used to as you have to press down quite a bit more on the keys. The touchpad is just like any other system, but the left and right click buttons are small so they too need some time to get used to.
The screen is perfect, bright and clear. The screen seems slightly brighter than the 600m's sxga and 6000's wsxga. Compared to the 700m, i have to say its no contest, the 700m's trubrite is nice. But if you are using this for business or even school, i still highly recm'd the matte finish of the X1, much easier to read under light. My system arrived with no dead pixels and even backlighting with no bleed.
As you know, the LX1 does not have any fans in the system so it does operate very quietly. But in a completely quite room you can hear a slight high pitched sound when you access the HDD. It is not at all noticable unless you are trying to listen for it.
One big disappoinment is the Heat this system gives off. During normal computing the computer does get quite warm, but when you fire up a game it really starts to get hot. It's not enough to burn you but sometimes it feels like its going to. Note once again it is only when running proccessor intensive apps like a game. This is one thing i hope they can resolve in future models.
Wireless and bluetooth have worked flawlessly. Using a Sonyericsson k750i and tmobile's gprs internet, i was able to get decent internet speeds connectiong with bluetooth. I also have a Kensington bluetooth mouse which sync's up easily with the dell bluetooth module. The Intel 2200 works great in my home, no connection problems what so ever, the wireless software is very easy to use for people not familiar with wireless networks.
The Build quality of the Latitudes have always been top notch and the x1 is no different. The magnesium alloy build makes the notebook feel very solid. Only small problem is that the battery tends to be a little loose, not nearly as much as my old Sony s170 but enough for me to notice. Battery life has been anywhere between 2-3 1/2 hours depending on what i do. I'm getting a extended life battery on thursday so i will post an update with the new battery. The compact flash and sd memory slots are very well integrated. Dell ships the system with a dummy sd card to fill the slot. The compact flash has a spring door covering the slot. One design flaw would be the absence of a charging indicator when the laptop is closed. The only way to tell if it is charging is to open the cover to reveal the battery light. The DBay was very easy to use and works just as well as an integrated CD drive. The single speaker is loud and clear, honestly sounds just as good as any other dell notebook, its just not stereo.
The case i'm using is a ZeroShock 12" case purchased off Ebay. You can also find this case at shinza.com. The case fits the LX1 with some room to spare, once i get the 6-cell extended battery, it should fill the case perfectly.

If anyone has any other questions please let me know. Better pictures of the system will be up shortly.

sweet review pogi........thanks alot, this will definately help me in the future when i decide to take advantage of X1 deals at the dell outlet...thanks again!

Great review, thanks for posting! Have you tried a D410 as well (just looking at your comparison pics)? If so, how would you compare the two (I'm deciding between the X1 and D410)?

Oh also, have you tried any RTS (or other non-FPS/3D) games on the X1? If so, how is the performance for those games?

Rome total war and C&C Generals ran ok, once again it depends on whats going on in the game. But overall not too bad at all, very playable.

Just though I would let you all know I finally got my X1 and it appears to be brand new. Not flaws what so ever. Not a bad deal for a machine that was nearly half off!

Wish I could pick up a dell outlet deal! Oh well. Just another quick question - have any of you tried to run an external monitor (1280x1024) with the ULV + GMA900 or dual monitors (laptop screen + external)? Just wondering if the ultraportables can handle this OK (I guess it should since the native resolution of the 12" screen is 1280 anyways) - just want to make sure!

Thanks for the review, Pogoboi. I've got my eye on an X1 and your review is very helpful. I'm interested in how the extended battery performs. Hope you'll keep us updated.

the x1 isnt really a dell. It's a samsung rebadged as a dell.

dell x1 is a copy of samsung Q30.

I would like to asking if someone was trying to use RMClock to undervolt the ULV processor in order to make th notebook less hot. I am just curious which potential for undervolting ULV processors have.

Another question, is it possible to overclock ULV PM? For me it would be useful to have a higher performance for short time in order to complete faster a rare processor intensive application I run on the way while not risking to overheat the system.

The ULV CPU won't benefit as much from undervolting when compared to the standard Pentium M chips. A friend got an extra 15 mins battery life and a slight heat reduction though.

I imagine it's because the low voltage chip is already extremely efficient.

I don't know whether it's possible to overclock these.

Pogiboi (or anyone else with an X1) - in the review you say you get 2.5 - 3.5 hours out of the battery. Is this with the standard 3 cell battery or the 6 cell battery?

Mine runs 1600x1200 external + laptop screen (dual mode) fine. Graphics is integrated so I'm not sure off the top of my head what the max resolution it supports is, sorry. I don't see why it wouldn't be able to do 1280x1024 for an external monitor.

I get around 2 hrs and 2x minutes when I'm watching a video on the HD with the screen at near max brightness (one step below) and also some surfing at times. This is for the standard battery.

For the large, I get around 4 hrs and 4x minutes on the same scenario.

I usually use just the large battery as then I know that I should be able to get 4 hrs no problem, if I'm typing, surfing, or working.

Great, good to know.

I actually would doubt your latter conclusion.

I made an experiment and restricted my 2GHz PM 755 processor to 1.1GHz. Then it was possible to undervolt it to 0.796V (and 0.700 at 600 MHz) which is, afaik, well below the specifications of ULV processors. I used the last version of RMClock for this purpose
(by deleting the processors speed steps above 11.0x).

If your friend got extra 15 mins of battery life from the original 2.5 hours on the small battery, it is about 10% drop. Using RMclock it is usually possible to gain 10-20% more
of the battery life and to reduce the heat respectively.

I am curious up to which voltages your friend was able to undervolt ULV 1.1GHz processor?
What is the minimal clock in the speed steps - 600MHz?

In view of my experiment, I actually don't quite understand what is special about these ULV processors, how they are different from the standard processors undervolted and underclocked.

It would be interesting to know the temperatures measured by mobile meter on the ULV processor under heavy load. Does the case of Dell X1 ensure a good passive cooling in this extreme situation? BTW, what is the case made of? Is it really a magnesium alloy (wow!) as it is written in the above review? I read somewhere that the Samsung Q30 original is made of magnesium alloy, but I was not able to find this information about Dell X1.

If someone knows about the overclocking of ULV processors, please write a comment!
