No Eff'n way do I want Internet (WiFi) Ad bloated books.
That does not exclude use of name brands within the story, but as others have pointed out, that can become rapidly dated.
As I see this: It's like Taxes. Once the Ad people get their foot in the door, it will be 'Just one more' ,one after another.
I subscribed to Analog SF &SF for years. IMHO Their Ad limited placement did not intrude into the reading experience.
BTW The K4 I bought is NOT the cheaper SO model.
