Just wondering if anyone can add to a discussion as to why any of the above flight computers are better than the others. If you were to purchase one, which one would you buy and why?

The one that you want is the one you don't fiddle with/stare at in flight. Cockpit displays can be an enormous distraction, and this is counter productive. The important stuff is outside the window.

I did my time on touch screen displays. There's a trackball equipped system out there. By all means, check them out. The alternative is a stick mounted remote with digital input (buttons to click). This isn't quite as slick looking/feeling at your kitchen table, but requires much less eyeball time in flight. No precision analog hand/eye coordination required.

I get jokes about the "wide screen plasma TV", but the point is: by making the display big and bright and extra-readable, it takes only a glance to get the info I need. The eyeball time is *really* small.

That's all my personal opinion. By way of disclosure, I do work with the ClearNav guys.
