Power usage

Rich, you mention the power consumption of the device.  I find that interesting.  Considering that power costs about $0.10 per kWhr, doubling that consumption is really just pocket change (or really a rounding error).  I wonder how much effort they put into getting down to that consumption.  Considering the cost of such devices, this is less than insignificant.  This is not meant to be a criticism of you or the article, or NI.  I just mean it as an observation on power consumption in general, and our facination with it where it really does not matter.

I see your point. But there are others tings that come into play (I think). For example, if you stack five of them together in a chassis, the heat reduction is somewhat significant, thereby reducing the need for fans constantly running, thereby lowing the noise.

Good point, Rich.  I was just reacting to the low number, but I see how it can be an advantage when there are many units used together.

I was anticipating what would come out of the aqusition of ettus research. NI has held up to what they said in the beginning, that they will stay out their business but release there own devices using the technology ettus developed. Looks good thus far. I am excited to see what will be coming down the pipe next, merging these minds together for the better.

The other issue with power usage, besides the $/KWH is the power source.  If this is going into a factory where you are just grabbing the power from the utility line, that's one thing.  However, if you are using wireless because the process you want to monitor is remote or mobile or a small independent installation, the power source itself becomes more important.

Since they are calling it open FPGA and one of the mission goals of open FPGA is "To define develop, and promote the use of open standards for communication between application programs and FPGA technologies," I wonder if programming with NI's VST is proprietary to Lab View or will it be able to utilize other software platforms...
