The feature that attracted me is the screen resolution of 2048*1536, most of the cheap ones are much less.
I paid AU$276 including postage but the price seems to have crept up a little since then.
One thing I wanted to try was to see how well it would run SDR software so here it is running SDR# with an SDRPlay (which is powered by USB from the tablet).
As you see it's pretty usable although a bit more CPU performance would make the drag tuning smoother. This really has to be the future of radio receivers and possibly transceivers. A big responsive touch screen showing the spectrum is a great way to see what's on the band. The SDRPlay has a particularly wide band so you can zoom out to find activity.
