I really enjoyed Acorn User and later Byte and Dr Dobbs. MagPi sort of has that quality now, but because there's so much information on the Internet now, I just don't think there's a need for that type of magazine any longer.
I would pay for something that I can hold in my hands and read that has deep detailed and interesting stories. I would love to have a new magazine that is somewhere between Dr. Dobbs and Byte.
To be fair, I pay for the Finance Times and The Economist right now because I find them to be worth more then the free information I can find on the web.
I am old, I know.
