No irony Evan. Every software effort has ongoing bugs and enhancements. The fact that Tophat is as useful as it is, while being free, is wonderful.. Big thanks to the developers, especially Robert Dunning!

I agree. I hope no one has misinterpreted my queries and comments. When I decided not to spend the money on a commercial flight computer, I was prepared to live with some lower level of functionality and higher level of UI aggravation. Instead, I've been amazed at how powerful Top Hat is.

I also think the TH team have mostly delivered on their goal of "Everything should be made as simple as possible, but no simpler" without giving up functions needed for competition.

I've occasionally brought my handheld device running Top Hat to dinner with pilots who own commercial flight computer systems and passed it around to get their input. Their reactions have been quite interesting. They've seen things they like better about Top Hat while at the same time commenting about things they think their systems do better. I've confessed to the aggravating hardware problems I've had and they've done the same. None of these is perfect. I suspect we'd all like to take the best from each to get the perfect product.

And, yes, all of these products--commercial and freeware--still have some bugs. That's inevitable; our soaring market is just too small to justify the kind of investment and testing that something built in the millions of units can justify.

Indeed, kudos to Rob Dunning's team. I've had the happy experience of seeing most of my issues resolved fairly quickly.
