First of all i like to say thanks for appreciating the cgarena magazine and yes this is the only free english pdf magazine which comes continuously from last 3 years without any break.
Print or online, its a matter of your choice. Generally print magazines read by everyone in the free time during break, in flights, trains etc... and pdf need to be read on the comp/mobile. If you love to read on computer or on your mobile then nothing can't be better than pdf's because you get latest content, they are cheap, you save the paper and trees too. Reading mag on monitor doesn't hurt your eyes then why avoid this...?
But that doesn't mean print magazines are bad some print magazine like gomotion, 3dworld are really good magazines which maintaining the quality in terms of content and printing. But there are some print magazines which is quite bad and created just for your money because they have old news, old makings which released already online long time ago and nothing new to offer. Those mag's are just for non-tech savvy persons and if anyone aprpreciate those then you can understand what he/she is talking about or some money indulge in this. Like recently one launched magazine with extra "t" is quite cheap in price for print mag but there is nothing in the mag which is new like some makings included in the magazine is more than 2 years old which also released on cgarena.
So, its your bet after all your hard earned money is going but both have some pros and cons.
