    That's called a laptop

    No, it is called proper tablet :-) One that has all I need and works for long time with high load.

    That's called a laptop ; ). I use Wacom tablets on my desktop for everything (mouse only for games)

  • Vitaliy_KiselevVitaliy_Kiselev

    Tell this guys make it thick and have big battery and 4 full size USB ports, and add Wacom stylus. I'll get one in this case.

  • _gl_gl

    I hope so, I'll post a quick review when I get it.

  • Vitaliy_KiselevVitaliy_Kiselev

    If screen is same as on my Kindle HDX it is very good screen.

  • _gl_gl

    Nah it'll be fine :). Bit of tweaking and some compromising with non-DPI aware UIs (I already have that on my desktop monitor with the same res). Sure some desktop apps will be a pain to use, stylus is probably best for small dialogs, but I don't expect a full-blown laptop replacement.

    Other reason to buy it was to download Pocket footage to a USB hard disk when I'm travelling. I know Android can do this, but you need special apps etc. So much easier on Windows.

    BTW just got an email that they have got them in stock today.

  • Vitaliy_KiselevVitaliy_Kiselev

    Don't you think it'll be all very tiny? As Windows still has scaling issues.

  • _gl_gl

    I forgot about tablets for a while, and then looked around again. Teclast have just announced the Windows 8.1 version of this tablet, the X90HD (same resolution): http://www.aliexpress.com/premium/x90hd.html?ltype=wholesale&SearchText=x90hd

    Supposed to be available in approx 3 weeks, I've pre-ordered one (edit: nope, turns out they got them today).

    Windows makes MUCH more sense to me, full hardware/driver support, any software you care to throw at it (including my own), any codec, IE etc. Sure it's a low-powered tablet with small screen so it's a compromise, but much more flexible than Android. I've never liked Android, it's OK on a phone but SO limited for a Windows power-user like me.

    Talking about the biggest storage for devices with a microSD slot, check this: http://www.ebay.com/itm/191059502130?_trksid=p2059210.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

    I got one, and it works with whatever card you throw in it. If you card takes 64gb cards, it'll take bigger.

    Cheers!

    Btw, if you read books you can get http://www.amazon.com/Certified-Refurbished-Kindle-Fire/dp/B00AFKC4EK/

    It is their first gen tablet with good contrasty screen and deep blacks, for reading book resolution does not matter much. And cases for it are best from that I have.

  • _gl_gl

    iPad? Cost, and not very flexible (no memory cards, no file access, limited file type support, no side-loading without jailbreaking, often can't jailbreak newest updates etc). And for 3D viewing you need a good 3D stills/movie player app that can encode the image correctly (most aren't good).

    The overlays also corrupt the 2D image, so you have to keep removing it. Annoying as they also require careful alignment. A cheap tablet can be used as a permanent 3D viewer more easily.

    H.265 support would be very interesting (smaller files too!).

  • Vitaliy_KiselevVitaliy_Kiselev

    Btw, one of HDX advantages is that it seems to be able to play H.265 videos, and may be even 4K in the future, as it has powerful CPU/GPU.

    Rockchip 3288 also much have something for H.265 as I remember.

  • Vitaliy_KiselevVitaliy_Kiselev

    All that is extra expense and more to carry though, when your Chinese tab could just use memory cards or USB storage (I assume it has USB OTG?). 3G isn't an option here in the UK (speeds are too unreliable).

    Just get fast Wi-Fi 2.5" HDD (or enclosure) with battery. In fact it must be faster to work.

    Yep, there's a few 3D overlay makers, and they all have various downsides and/or don't support the devices I'm interested in. Long story for another thread.

    What is wrong with iPad? Retina ones have good screens.

    You mean like a WiFi or Bluetooth hard disk? I hadn't thought of that, that could work. All that is extra expense, more batteries to worry about and more to carry though, when your Chinese tab could just use memory cards or USB storage (I assume it has USB OTG?). 3G isn't an option here in the UK (speeds are too unreliable).

    OK. But I still do not get why you can't use wireless storage, for demos you do not need 100-200Mbit videos. And under 50Mbit it works fine.

    Check https://play.google.com/store/apps/details?id=com.aromamedia.eassee3d

    Also check their site, they seems to make overlays for retina iPads.

    I have an LG passive monitor (I edit my 3D videos on it). Yes they work better, but the FPR (polarizing film) needs to be built into the screen, you can't retro-fit one. I haven't heard of any tablets with them.

    Active glasses require a 120Hz or better panel, and I still don't like the flicker. Plus bulky glasses, batteries that run out etc. Glasses-free makes more sense on a tablet. With eye-tracking (done right), it could be v. good.

  • Vitaliy_KiselevVitaliy_Kiselev

    The narrow sweet spot of 3D barrier technology panels is a problem, but I can accept it on a good quality display. Eye-tracking could correct the sweet spot issue (for 1 viewer), but nobody is doing it yet on portable devices

    May be make instead polarizing ala LG? And passive glasses?

    I also thing that you can research into making active 3D player without any screen mods, as modern active glasses are driven by bluetooth.

    (I haven't found any shot yet that shows the subpixels - the damn thing is just too high-res, and no closeups.)

    I need this for demoing high-end content on the move, so the movies need to be on-board or on USB storage.

    I have the Gadmei E8-3D, a Chinese tablet with switchable 3D parallax barrier (same as your device VK, very narrow sweet spot). Awful 1280x800 TN panel with bad viewing angles (each eye sees a different brightness!), low blue gamma that can't be corrected (colours are cold and pale) etc.

    I want to store a ton of high-quality 1080p H.264 videos, and 64GB is pretty limiting for that (I've been using a 128GB USB stick with my Gadmei E8-3D tablet and even that's full).

    How much high quality? You can check things like http://www.amazon.com/gp/product/B00CSFCYFY/ or http://www.sandisk.com/products/wireless/flash-drive/
    Wi-Fi must be pretty good with good router as it is 2x2 MIMO on Kindle.

    Also, why you are storing high quality things for tablet? May be just make small batch conversion? H.264 encoders are quite fast now.

    The other important thing for my 3D application is the RGB sub-pixel layout. They need to be vertically stacked (in landscape mode). Does anyone here have a Kinde HDX 8.9?

    Just search for reviews, some have macro shots. I think it uses same layout as in IPS panels without any extra white pixels and such.

    As for 3D, I have 1280x800 photo frame that can also play side by side videos. Not very impressive thing (due to very narrow spot and not impressive panel).

  • _gl_gl

    The catch with the Amazon tablet: no memory card slot, and no USB OTG support (for USB storage devices). Well, someone said that you can root & patch the firmware for it (unconfirmed).

    I've long said that mass market displays need to be factory colour-calibrated, so that people can trust colour accuracy, especially when shopping. I had not heard that Amazon are doing that now, but it makes perfect sense for them. After that we need mainstream wide-gamut.

    Just look around, as I said, Air and HDX are very accurate and good. XPS 18 is also very good.

    It all depends of manufacturer. In fact, good and properly calibrated display is not very bug seller for casual user, and it usually lead to shorter battery life. So, it is usually present with brand tablets were they invest max into best battery and best power management.

  • _gl_gl

    Thanks VK, I wasn't aware of this one but I'll check it out carefully.

    I suggest to check Kindle HDX also, just spend some time and get used or refurbished. Will be faster plus you will be absolutely sure about calibration and screen (Kindle say that they make special calibration to get such accuracy) . Teclast wait can last for long time.

    Here is cheap

  • _gl_gl

    Yeah, I know about the Nexus 10 and the colour rendering is pretty bad. I also don't like the rounded shape. With yours VK I don't like the white case (black works much better for media). But the specs are good, might grab one.

    Just remember that 8.9" panel is much better

    The Amazon Kindle Fire HDX 8.9 and Apple iPad Air are both even more impressive on another performance level because in addition they deliver top notch picture quality, absolute color accuracy, and accurate image contrast that is not only much better than any other Tablet, they are also much better than most HDTVs, laptops, and monitors. In fact, with some minor calibration tweaks they both would qualify as studio reference monitors
