Hope it's as good as pFSense. Was looking at one of these too, but doesn't really do anything more than pFSense?
I am attracted to it cause it means I can pull a SFF PC out of my rack, and replace it with a much smaller unit. Perhaps that is the primary benefit of this unit!
That is exactly why I bought it. Power savings over the SFF PC. I don't expect much in the way of feature/performance gain, but it would be a nice surprise.
As a side-note. I ordered the unit yesterday afternoon late and DoubleRadius will have it at my door probably before I get home today - at the UPS ground rate. Can't beat that!
