This is true, depends what you'd use it for. SD, as well as being a brilliant (IMO) nav app, will also deliver real-time (with 4G) weather, NOTAMs, circuit patterns etc.
Compared to the extremely expensive Garmin 750 I fitted in our panel, SD is more intuitive, more feature rich, much better suited to VFR ops and a damned sight cheaper.
I don't work for SD by the way...
