You are comparing Apples and Oranges. The Viewsonic is the equiv of the Crestron hand held touch screen, or the small iSYS panel, which doesn't do all those things, for probably the same reasons that the Viewsonic doesn't, becuase they depend on standard wireless connections and battery power.
For the bigger ones, they are not portable, and they are no different from CQC running on something like a Nobu or a Planar integrated computer/touchscreen system, and yes on those platforms, since they use wired networking, they can stream video and audio and all the other things that desktop computers can do now. And Crestron didn't do anything to create a video scaler, that's part of Direct-X and standard video cards, and it's the same scaling that all software video players use. And their acceptance of various video formats is nothing that people aren't doing with their HTPCs with standard video input cards.
The only real difference is that they are using Embedded XP (and, BTW, there is no 'Crestron OS' on this thing, it's just front end software of theirs that talks to their back end), which allows for a very stripped down environment, more so that you can achieve with standard XP. But you can strip down stand XP pretty extremely, and yes when my system boots up it boot up into the interface viewer.
|What is different is that you do not need to launch an application to use the tablet to control your system. No browser required. No executable file needed.|
Yes, there most certainly is an application. You just don't see it being launched, or it is auto-launched on startup of the panel, but that's it. It's clear that they are just running their own client side software, nothing more. They aren't part of the OS, they are just another application. Embedded XP is the OS.
They have just created what is no different from what we can provide, they have just put it together into a nice format that we cannot afford to do at this time (though we can use things like the Planar or Nobus integrated machines.) And they are using Embedded XP (on the larger two boxes, CE.Net on the smaller one AFAIK), which allows them to run a diskless configuration. We will be addressing that before too much longer, in exactly the same way.
I'm not claiming it's a piece of trash. It's a good box, but there's no technology in it that is unique in any way that I can see. It's just a collection of technology that anybody with a reasonable R&D budget could field, well packaged into a slick enclosure. But it's using straight off the shelf technology, and other than the diskless e-XP configuration and pretty enclosure, it's nothing that an HTPC running CQC couldn't deliver at this time. And they are just charging a ridiculous price for what is effectively a slick integration and packaging job.
