I am blown away! I just received my touch screen upgrade and the WiFi dongle and I can't believe how well the system works. You guys are the best. I have a well thought out touch screen EFIS with the ability to instantly transfer flight plans from my iPad. The touch screen response is silky smooth and the human factors design is incredible. I can still use all the knob commands and augment with touch naturally. You guys are the Apple of the Avionics world! I'm not usually one to gush but you've got a fan here. Wow ;D
