100% agree. I do contract flying, and its invaluable to me. From having the whole US sectionals, low/high enroute, and of course the IAP's at my fingertips you can't beat it.

I do not use the georeferenced IAP'S , never felt I needed that, but the basic version does put you on the other charts. I did use this once in a luscombe I borrow as my primary source of nav(no electrical in the plane), worked great and I only use the built in GPS receiver also.(accuracy was fine)
