You can get LOOP and its fellow magazines downloadable through a free app for the iPad. It's a bit gadgety to read but there are usually some interesting articles in there, and nothing to complain about cos it's free!
I liked the AOPA magazine a long time ago when I had a subscription, but the problem is that it costs so much to be a member / subscribe; along with all the other organisations that could be considered it just got too much.
I do read the LAA magazine which is usually reasonable value for money, imo.
