    I noticed that too, it´s funny when the deeply interested starts to discuss everyone else seems to "give up". However, the sky i completely clear here so I ceased the moment and grabbed some pictures of the outdoor screen.

    The screen when the sun i shining on the computer, but not straight on. The screen works perfectly well.

    When the sun shines straight on the screen. I tried cover the screen as little as possible with my shadow to get the absolutely worst condition as possible. I noticed that the reflected sun is smaller in reality than on the picture, which could be because of my cheap camera. But the screen does a very good job and keeps the sun as a single spot and not over the whole screen.
    [​IMG]

    My cellphone at the highest brightness. As you can see so became the phone useless because of the reflections from the sun and sky, but the computer is still very usable.
    [​IMG]

    To show how well the anti reflective layer works so did i take a picture like the first one, but with the cellphone beside. You can barely see the reflections on the computer screen while the cellphone clearly shows the reflection of me.
    [​IMG]

    Finally, the "light wave" problem. I have tilted the screen to the angle when the light shifts is halfway through the screen. As you can see so is the bottom half lighter than the upper half.

    My verdict. This is the most amazing screen I have ever encountered during harsh light conditions! I have been doing all this with the sun shining on the screen and it works like the first picture, like a charm!

    But the problem is the "light waves". Especially noticeable is when using the computer in portrait mode. But as you said, Steve B. If you accept the light waves so will you probably have among the best screens on the market.

    I have heard a lot of people speak very high of the iPad 2 screen, so I managed to grab one and make some comparison.

    When the sun shines through the window. You can clearly see the benefits with the outdoor screen with it´s anti reflective layers, where my reflections is almost invisible. However, I´m still impressed how well the iPad 2 performed.

    In low light environment and at the same brightness so did they perform close to each other. For us, the x201 seemed to have a little richer colors. However, the difference became more clear during harsh light conditions.

    And I didn´t compare when the sun shines on the screen since the iPad 2s reflected the sun so bright it become unusable and blended the camera.

    Andre, it's very cool to see you put up those posts.

    This is a bit of a re-post, but I compared the t5010 to the x200t Superbright Outdoor last month in a different thread. Here are the pics. They're pretty self-explanatory. As an outdoor viewable screen, the x200t S.O. is the best I've ever encountered personally. I've recently been using an older le1600 View Anywhere for art as well (it's got lots of buttons!), and I took it to work outside some, as it's supposed to be outdoor viewable..... sadly, no. Perhaps to read text if you needed to. I've been very spoiled by the Lenovo screen. It really is spectacular.

    As before, the worst things about it is that it really makes using the slate in portrait mode practically useless to me because of the "valley of shadow" that cuts vertically across it. It's wonderful however in Secondary Landscape though- my orientation of choice.

    Here's the comparison pics. Lenovo on left, Fujitsu on right.
    Inside, with some glare coming form the window.

    Outside, facing up. Cloudy day.

    Held in my arms in secondary landscape. The "digital checkerboard" effect only appears in the photos- perhaps the anti-reflective coating at work? But you still get a sense of how clear and vibrant the screen is.

    Fujitsu in my arms. Readable if tilted, but with a lot of reflections.

    That T5010's really reflective...I hope they fixed that on the T901, which could be my next convertible in a few years.

    I noticed the same "light wave" issue on my 2730p with AFFS+ panel (BOE098B, the supposed "indoor" variant), but that's the only real complaint I have with it. It's surprisingly readable and not as reflective outdoors, not to mention that it gets bright. Really bright. Almost eye-searingly bright at maximum settings.

    The X200t outdoor screen is another variety of AFFS+, right? Check the monitor hardware ID with the Device Manager or Everest/AIDA64, just to be sure.

    I believe it's a PVA panel? It's out at the repair depo right now, so I don't have it to check. Should have it back some time this week though.

    Btw, I'm looking into the HP's and their Multitouch Outdoor screens. Is there a 2730 that's Multitouch and Outdoor? Or is that something that only came along with th le 2740? Do you have any experience with these HP Outdoor screens?

    No 2730p has finger touch capability. That was introduced as an option on the 2740p, and then standardized on the 2760p. (It would be nice to have, but it's not something I'm willing to pay the few hundred dollars of a premium that the 2740p still commands.)

    It seems that the 2730p had BOE Hydis AFFS+ panels fairly often along with the usual Samsung PVA panels, but the AFFS+ ones seem to be less common on the 2740p and 2760p unless you specify an outdoor screen. Even then, it seems like the AFFS+ option wasn't brought back as the outdoor screen option on the 2740p until later in its lifetime, which partly explains the rarity in its case.

    Panel lotteries are so irritating. At least the Fujitsu T5010/T900/T901 line is guaranteed AFFS+, though the changed monitor hardware ID threw some of us on this forum for a loop before.

    With my x200t in the depot for so long, I recently picked up a Motion j3400 slate, supposedly the king of Outdoor Viewability. I decided to shoot some comparison pics.

    My verdict? It is also very very good. They're both good, but both different.

    The x200t is smoother, clearer, and a bit brighter (and feels a bit like writing on glass; there's almost zero friction), producing more reflections, but you can easily see through them. It's AR coating produces the shadowy "waves" of which we've spoken much in this thread. They're a bit of a nuisance, but you can move the screen to the right angle, and when you do you have a gorgeous screen that works wonderfully outdoors.

    The j3400 is sort of matte (and even has a nice bit of texture when inking), with almost no reflections at all, but lacks the sort of clarity of color and image the x200t provides for indoor work because it has a sort of "sparkly" effect. I'm assuming this is how it's own AR coating reduces reflections, by refracting light in microscopic ways, or some such thing. My understanding is that this is an affect seen in many AFFS+ screens though, so it may not come as much of a surprise to others. It reminds me a bit of my Motion le1600 in this way, just with a brighter screen and more sparklies that make it more viewable outside.

    Both screens are very very nice. Easily the two best screens I've had. The j3400 is clearly my preference for inking, the x200t for clear graphical quality. The screen on the j3400 is Gorilla Glass and is rock solid, which is very nice to write on. The x200t is some sort of semi-hardened plastic, which has a reasonable amount of give if you press with any decent pressure, which I've never really cared for.

    The clasping hinge system that the x200t uses for closing the lid has a bit of give to it too though, and I think it was adding to this problem. This means the actual body of the screen (or the black "frame", as you will) will actually have a bit of up and down movement when you want to use it as a tablet and apply force with your hand. I recently solved this by attaching a thin (1/16- 1/8") black rubber "foot" on one of the outside corners of the back of the screen. This helps create a more consistent experience of pressure between the back of the lid and the body of the hand rest when the computer is used as a tablet. As such, there's less movement from the screen, and this has made the inking experience better on the x200t. Still, even so, the plastic of the screen has a bit of give, and isn't as "solid" as the feeling of the j3400. It's better though, and much improved. It had been one of my complaints about the x200t as a tablet, and this solution may have improved it enough to be considered a solution to me.

    Of course, the j3400 doesn't have this issue about "give" in the screen at all. I also have to say that I prefer a bit of tooth when inking, and might be adding a mild Anti-glare screen protector to the x200t to improve that experience. Of course, that'll probably create some noise, and it'll probably also slightly reduce the outdoor viewability on the x200t. And that may take away that "crystal clear" color experience you get on it comparative to the j3400. As such, it may be that the j3400 is the better all around screen.

    It's all about trade offs, and the major issue for the j3400 is that, regardless of how viewable the screen is outside, or how pleasantly firm or textured it is for inking, or how much I like the build or the onscreen buttons, the x200t still performs admirably in these categories (if perhaps not quite as well??), and is better, IMO, as an all around computer while still being amazingly viewable outside. It has the added benefits of being easily upgradeable, has better battery life, is slightly more powerful, and (most importantly for me) has a very good keyboard that's always available.

    I think that, for a person that really wanted an outdoor tablet/slate with a full array of ports that they could then dock at a real desktop and run their office from with a real external keyboard and mouse (not the crappy mobile keyboard that Motion offers!), the j3400 might actually be the better performer. I don't have a desktop though, and so really needed something that could be easily set up at the dinner table or at a cafe. The j3400 wasn't quite right for that usage and so doesn't seem to be a good match for me.

    Here's the pics, btw. As usual, any kind of weird moire pattern on these shots is really more about how the screen reacts to the camera. None of that is there in real life. In fact, both screens look noticeably better with the naked eye, and I have little to no problem reading either of them in the sun. Oh, and both screens are finger print magnets, IMO, but the fingerprints don't really affect either of them when really in use. Just thought I'd add that in.

    Are all x200 touch screen?
    I saw one listing with 2.4ghz dual core. It didn't say that it was a touch screen.

    That would most likely be the laptop. You have to search for x200t or x200 tablet on eBay to get the tablet of model. Theyre all 1.86 core 2 duos.

    Yes, you have to be careful on ebay. Some sellers list the laptop under the title of x200 tablet too. If in doubt, and if there's not a picture of the actual system, I would send a question asking if it is multitouch, or pen only. You can also ask for the model number and then google that to make sure it's the tablet.
