There are some good online mags out there, some not so great same goes for printed mags.
As far as them replacing hard copies? I don't think so & I would not like to see it, I hate reading a large amount of text off a PC monitor. The only one I buy with the intention of reading cover to cover is FF&FT, it has some different stuff in it to the other main mags and Magnums reviews are the only ones out there worth reading, period. I wish there were some bigger reviews carried out in FF&FT, something along the lines of those carried out by the other popular mags but in a more objective and less nonsensical confusing fashion.
Cheers
