Can't speak from experience, but purely repeating what the article stated.
I DO like the idea of all the bells and whistles that a PDA can provide. DO NOT like the idea of having to try and reset a PDA in flight (at a less than opportune moment)
I wouldn't be using as my primary navigation (until the VOR gets kyboshed) so, I'd rather have a dedicated piece of kit. Besides, those 196's look ultra mega whizz bang marvelous.
Of course, iPaq plus GPS add on and software is 1 large here in the US, which is precisely what the 196 comes to......decisions decisions.
Think I will stick to VOR, DME, ADF and a chart. For now.
