Is VD actually better than USB link? If that's the case, I might look into buying it. I thought that the post reaffirmed this, but I may be wrong.

I was under the impression that the inconvenience of using a USB cable is compensated by the higher throughput/lower latency of using a direct cable connection vs. a theoretically more limited wireless connection. Does VD simply have a better compression algorithm than Link, or can it actually push through more data?
