I'm a new pilot and want to get some type of active weather on a portable device. I see that on iPad there is WingX and the Garmin App that integrates the ads-b if you get the receiver. I've read somewhere that foreflight was considering intergrating XM weather. Then there are the portable Garmin devices like 696 or the aera devices. Since the ads-b is without a subscription, that seems really attractive, but some pilot friends said they didn't think that there is good coverage with it yet, and it was slower turn around time updating the weather than XM.
Does any one have experience with the iPad apps and ads-b?
Any preferences or pearls of wisdom?
