The reality is not everyone reads or wants pure digital content
Frankly I'm disappointed at your decision to drop the paper copy. I've been a subscriber since you started publishing and like paper media. I appreciate choice, which is why I use Linux and subscribe to your magazine - what you are doing is taking away the very choice you have so long been a proponent of.
It may surprise you to know that not everyone has an iPad/tablet/iphone/kindle/nook or smartphone for reading digital media. I travel a lot a using these devices is often not practical.
Shame on you for submitting to the Apple generation!
