I recently braved the enrollment, initial D/L and subsequent chart update processes for my Advanced Flight suite. There were glitches with the app, but we got through them for the most part. The whole time I was futzing with the hardware and software to accomplish this on a MS-DOS platform, I was thinking "TSRH is why we can't have nice things..."
There's a reason I'm surfing VAF on a MacOS platform this morning. Offering aviation software that only plays with the IBM side is, in my not sufficiently humble opinion, sketchy customer service from the start.
I hope Seattle prospers and remains in the market, because they are AFS's chosen service bundler and they have my money We need a new meme: everyone wants to run cheap generic DOS hardware until it's time do DOS things.
