Here's a data point:
I was one of the leaders in bashing SA about a year or year and a half ago when they had some serious problems with both download and support. Then they revamped their download software, and I have had no problems since.
After reading this thread, and in need of an SA update fix, I downloaded an update this morning. I have 16 states, a USB-2 drive, and running Win Xp. It took about 3 hours on a 10 Mbs connection. The program asked at the outset whether I had SV Ver 13 - I said yes - and it did its thing.
So, I had, and have had, no problem, since SA changed their update software. Like I said - just another data point. Because, some people have major problems, and some have none, it could well be this is related to the user's equipment. It was for me way back when, which is why I switched from a Win 7 machine to Xp. Once it worked for me, I stuck with it. I'm like that - if it ain't broke, you know.... Maybe a lot of the complaints should be directed to MS Redmond. It won't be their first. You DID say, Jon, it worked on a Win 7 machine, but not on a Win 8. Big clue there!
Those who think Dynon should shoulder the problems at SA, might contemplate adding MS as another third party supplier that is screwing up the works. Good luck there!
What I find somewhat irksome is this incessant drumbeat threatening to go Garmin, or stating "That's it - I'm going Garmin." What's that line about "don't let the door....."
I have some Garmin gear, played with their stuff at the shows, talked with their people. I sure don't think they win this horse race hands down. Having SV Touch, I know first hand what a touch screen is like in rough air. I sure wouldn't want that to be my only interface, or I'd go back to steam gauges.
All glass panels have a lot of Wow! factor - I'd say Garmin and Dynon are probably a push and very subject to personal preference.
As far as after sale support and service, I don't think there is any comparison. Dynon is clearly the class act of the industry. For me, that's a VERY major consideration in any high value purchase.
Now, in writing this, I decided to saunter over to the Garmin Forums to see what's going on at the Big G. After a half hour googling and searching Garmin's Forums, I've yet to find anything on the G3X. They need a log-in and password to even get in - and I have them. But I can't find any Forums for the G3X. Maybe someone else can supply the url.
Or maybe there isn't one.
