More specs of Dell’s Latitude XT tablet PC

DellEven if you don’t own a Dell computer, there’s a lot to thank them for how they have changed the concept of buying and selling factory-built computers. Besides being extremely competitive, they’ve also made computers customizable inside-out for all segments of the market both in the home and business. Which is why when Dell (finally) announced their Tablet PC offering, every tablet enthusiast scribbled with joy, including moi. Many believe and hope Dell could set the Tablet PC industry right, even if price is all they’ve got.

But according to internal documentation (above), Dell’s first Tablet PC, Latitude XT, was intended to ship in most regions outside America last Friday. Unfortunately it seems to have suffered a delay since it has not appeared on any Dell’s regional websites. The delay might be related to the recent LCD shortage.

On the bright side, I do have some official technical specification information for the Latitude XT, more or less confirming the leaked specifications from a month ago.

  1. There is no specific “multitouch” model, and I’m pretty sure that the 16:1 is no typo. apparently you don’t get around the internet quite enough because I’ve seen other widescreen and pan-scan formats, one of which was 16:1.

  2. @Danny:
    I think it is Multitouch, I remember a video coming down through my Outlook RSS reader last week demonstrating this.

    Here’s to the hoping the price is less than the other guys, thats the only thing stopping me from getting a (decent) tablet.

  4. It’s not going to be multitouch – it’s a capacitive screen, which means it needs a pen.

    What gets me is that it says it’s PATA. If that’s true, this will be the first PATA system Dell has shipped in the business segment in about two years. It’s got to be a typo….

  5. (That is to say, is the Red flag linux a clean install, or does it have to be altered by Dell to work right?)

    …and which costs more, shipping from China or the Windows tax? Not all Americans want Windows on their machines– just 90% or so. 40% don’t even know what they want, and most of the time, Linux will do just fine for them.

  6. Also, Dell has stated that this tablet IS multitouch. See this article:

    http://www.computerworld.com/action/article.do?command=viewArticleBasic&articleId=9046999

    “In addition to the green initiative, Dell also announced the new Latitude XT tablet PC, which he said is the industry’s thinnest 12.1-in. convertible laptop and has a 25% brighter screen than those on competitors’ laptops. It will support new ‘multitouch’ technology, said Kevin Kettler, Dell’s chief technology officer, during an onstage demonstration.

    “In addition to supporting single-touch features that work with a user’s finger or a stylist, the laptop will let customers use multiple fingers to draw lines or manage images simultaneously, Kettler said.”

  7. Charlie is right. It was rumored a while back that Dell would be sourcing their digitizers from a company called N-Trig, who combine passive capacitive touch with active pen capabilities in a single unit, so you get the best of both worlds. They’ve also stated that future versions of their capacitive touch technology would be capable of multitouch; I assume what Dell demonstrated at Oracle is the future version of that digitizer.

  8. I suppose if it’s multitouch it might be the same kind that Lenovo is using for the X61, which utilizes both an active digitizer pen and touch input. These two are different and independent input devices in terms of the actual hardware.

  9. Actually is not the same kind that Lenovo X61t employs, it’s capacitive (reads input from the electrostatic/electromagnetic response of the fingers/pen on the screen), Lenovo’s is pressure(touch) based for the passive digitizer combined with active digitizer for the pen, and the pen on Lenovo if close to the screen disables the passive digitizer (touch/pressure control).

    So in THEORY it’s much better, except that we don’t know yet if Dell’s capacitive is able to reject palm input to avoid vectoring while inking.

  10. Dark, that sounds interesting. But this also means no more cool pen-hovering over the screen without clicking, right? I hope this type of touch screen is also more power efficient.

    Are there any battery life numbers so far on the 6 cell?

    Did dell claim this is the smallest 12.1″ tablet? .. Doesn’t this weigh a bit more than the Lenovo X61T?

    Either way I’m happily typing away on my Fujitsu T4220 with SXGA+ Screen, and until someone makes a higher resolution small screen tablet, I’m sticking with this. Its really the only option for those who want a decently high resolution on a Tablet PC.

  11. Interesting choice between a thinner/lighter 220 nits LED-backlit screen vs a 400 nits dual-bulb CCFL-backlit screen that has digital array microphone and ambient light sensor. I think I would go for the CCFL, but then again I’m not sure how much thinner and lighter the LED is. They listed 3.57 lbs for LED version with 4-cell battery, vs 4.0 lbs for CCFL version with 6-cell battery, which hides the true weight saving of the LED?

    I’m also really confused with the mention of the D-Bay drives *and* Media slice drives.

    Engadget’s interpretation is that “An integrated media bay can accept either an optional secondary 80GB hard drive or a dual-layer burner”.

    So it has an integrated bay for an optical drive, a 2nd hard drive, or a 2nd battery? And it also has an optional docking base that has a separate bay for even more drive/battery options?

    Anyways, I’m disappointed that there’s no webcam. But I like having both trackpoint stick and touchpad. Actually I like the stick but I know most people like the touchpad.

  12. Windows Security Button = CTRL+ALT+DEL, handy if you’ve got the keyboard folded away.

    I’m looking forward to this, hopefully I can blag a demo model from our Dell rep….

  13. Great job on the specs. Yes, it looks like you have it right with capacitive touch – I think the technology comes from a company called N-trig.

    There are a couple of other blogs that talk about them as well.

    Comment on Tablet Buzz…doing the same thing- connecting the dots on Dell and N-trig working together.

  14. Great job on the specs….a little disappointing on the processor speed. I would most likely go for a fujitsu or the lenovo first for the convertable tablets but the sahara for the slate (way cooler)

  15. I noticed one thing that concerns me deeply regarding this new Dell. Where is the scroll button while in tablet mode? Is the biometric reader going to serve double duty like some or is there no scroll ability like HPs 2710p. Without good scrolling ability in tablet I cant use this machine as it loses a function that I use with regularity.

  16. Release date… My dell rep told me last week that they have an internal memo to start selling the XT to business customers on 12/11/07 in the US. He would not confirm or deny the rumor that retail purchases will have to wait until CES in January.

    I’ll be calling him early on the 11th. :)

  17. I had a chance to play with one of the demo units and it isn’t as good as Lenovo or HP. Optic is BAD and there is a “grid” like reflection from the display probably related to the touch module.
