I used SbS 2 years ago, on a Blackberry Storm. I think the only reason I moved away from it was that I switched to an Android and they hadn't yet released the Droid version. I mapped both courses at my local club very quickly and easily and they were available to me in very very short order.
I've been using SkyDroid since last year, only because it was available at the time for $1.99. I may switch back to SbS, my issue with SD is that it reset my phone so much. Sometimes 4 or 5 times in a round. It doesn't do it when I'm actually using it, I hear the phone restart.
From what I remember, the emails from SbS were a little goofy, the 'off color' humor ones weren't exactly my flavor but it's not a deal breaker. I also remember Travis being very cool to deal with, any questions I had were answered quickly.
I think I'll give this a go again, and might even pay for it this time :)
Are there any known bugs on the Android version of SbS now? What's the battery usage like? My Samsung Galaxy Nexus is kind of a battery hog already. One thing I do like about SD is that when the screen is off or the app is in the background it doesn't utilize the GPS, saving battery.
Make me a user again Travis!
