I dunno, I'm having trouble getting excited about this, especially since it uses Android. I'm currently using an SDRPlay RSP1 w/HDSDR on a 7-inch Windows 8.1 tablet and its a fantastic portable combo. I've tried the android SDR apps - SDRTouch etc., and to be honest they (SDRTouch at least) has a long way to go before it is as useful as its Windows counterparts.
IMO, a better device would be similar in concept but MUCH more rugged, would have external power options in addition to the built-in battery, would have an embedded operating system which is optimized for both SDR and web/network use, and a single good embedded SDR application program, with ability to upgrade.
Touch screens are a double edged sword - they are convenient but annoying also due to unwanted actions resulting from unintended touches. And as operating systems go, Android is way too dumbed down for serious use.
I can see though where the market for this is at <$100, and it will definitely appeal to the less technical who want a pretty good do-it-all portable
