    The best way?
    By that you mean just as dim and no 3D? That is a very odd definition of best.

    Actually, that probably *is* the best way to watch most 3D films. Few 3D movies use 3D as more than a gimmick.

    "3D glasses" are polarized sunglasses. Why do you think they are two separate things?

    It's the orientation of the polarization that makes them different.

    3D glasses have the polarization rotated 90 degrees between lenses.

    Polarized sunglasses have the polarization oriented in the same direction.

    You wouldn't want to wear 3D glasses while driving, because your vision would be different between your eyes - you'd see some reflected light with one eye and not the other.

    Or red/blue color blocking, or LCD shutters. (which I guess technically rely on polarization, but that's not how they get the 3D effect - mechanical shutters would work just as well).

    No. I just tried with a pair on my screen. On this Dell LCD is seems to increase the distance between the text and the glass(plastic)? So whatever polarized coating they use in manufacture, gives all of the head ache and none of the 3D effect.

    HOWEVER! Just one lens is fine. So using two rights of lefts will be fine and is the best way to watch a 3D film.

    Turn your screen 90 degrees and the polarized glasses should take care of 100% of the glare. On most LCD screens, it will make the image go completely black.

    Which is always amusing when places use a monitor turned 90% as an information display - one bright sunny day we walked into a fast food restaurant and my wife asked me what I was going to order, while she pointed to the blank screens. I couldn't figure out how she was reading the menu until I remembered to take off my sunglasses.

    What I don't know is whether monitor makers purposely chose a polarization direction that works well with glare reducing polarized sunglasses, or if it's just coincidence that the best polarization direction for a monitor also happens to be compatible with sunglasses.

    You should have taken the calculation further. That works out to $180/year plus your $50 for the stick itself. I hate to burst Dell's bubble, but at $230 you can get a cheap desktop computer from any number of suppliers (think office machine with minimal 3D support) and own it. By the time you're into the second or third year, you've paid for a pretty nice machine compared to Ophelia.

    I'm sure Dell's executives cream their pants when they think about raping the population for $15/month or more, but as Microsoft's earlier efforts with web-enabled software show, most customers aren't willing to sucker in for monthly fees unless they can write it off as a business expense.

    You'll note that I quoted prices for an Amazon EC2 server running Win Server 2008 - who knows what Dell is going to charge for a home Win8 session?

    If they are providing a service to users at a price they are willing to pay, why is it "raping the population"? Is a restaurant "raping" you when they charge you $30 for a steak that cost them $5? Are you being raped when you buy a $60 shirt that only has $2 of raw materials and cost $3 of offshore labor to make? You could cook your own steak or sew your own shirt at home for a fraction of what it costs in the store, but most people are willing to pay for the convenience of having someone else do that work.

    And businesses don't want you stuffing their PC in your shirt pocket and taking it home with you for an untold number of legal, ethical, and control reasons.

    That's funny, my employer issues everyone a laptop and encourages them to take the laptop home to do work - and they have a lot less control over what I do on my laptop than on what I do with a cloud based virtual PC.

    Oooh, this is a fun game.

    Bluetooth $5.56 (http://www.newark.com/dynamode/bt-usb-m2/adaptor-bluetooth-usb-class-1/dp/39T4089)

    total: $56.94

    So you came up with about the same price as me, for a device that's more comparable to Dell's device than a raw Pi with no case, and no wireless connectivity?

    That gets you hardware that is presumably more powerful than what Dell is pushing (because it's not just a dumb terminal) and can be used to do other things than connect to Dell's cloud.

    Why would you presume that a Pi is more powerful than the Dell when Dell hasn't released specs? Just because the Pi can be made to do anything you want doesn't mean that the majority of consumers want to have a device that they can load any software on -- many consumers want a device that they plug into their TV, and then 2 minutes later they enter their credit card number and suddenly they have MS Windows running on their TV. (the fact that it's "in the cloud" isn't relevant to many people. Oh, and Dell said that the device will have a local web browser and other apps, so you won't need to connect to the cloud for everything.

    The $25 pi will bring that down to under $50.

    But is the model A's 256M of RAM sufficient to run Wyse's thin client software? Oh, and don't forget to add in the cost of a USB hub since the Model A has only one USB port.

    Integrating the wifi onto the board and dropping all the other ports the pi has would also reduce the price considerably. And there's no way Dell pays $6 for plastic boxes in volume.

    If a bunch of amateurs and small volume companies can offer that price, with considerably more capability,

    The Rasberry Pi was designed by a non-profit with mostly unpaid employees to be as affordable as possible - why do you think Dell's designers can come up with a new design more cheaply than a team of unpaid engineers?

    $50 for Dell's loss leader hardware for their cloud service is a pretty crappy deal. They should be giving you the thing for free.

    If they gave it out for free, then they be giving thousands of them to geeks that just want a free Android device.

    And "Dell's software?" VNC clients are free. Sorry, I meant VNC clients that don't send your data through Dell's cloud for perusal.

    VNC may be free, but it's not going to offer the same performance and features as Wyse's thin client software.

    It's clear that you're not a candidate for their offering, but that doesn't mean that it's a bad product for their target market. Some people will welcome a tiny device they can plug into the back of their TV and act like a full-size desktop PC. One potential audience would be the business traveler that no longer needs to carry a laptop with him, he can just carry this device in his pocket and plug it into the hotel TV (where they also provide a bluetooth keyboard), the business center PC at the airport, and when he goes to the client to give a presentation, he can plug it into the MHL port on his client's projector. And since it's integrated with Wyse's Cloud Client Manager software, the employee's IT department can manage it remotely.
