Then do some more reading about the topic and stop being an ignorant idiot, spouting bullshit about things you know nothing about.
Well, the analogy is between two different mediums, digital and physical. Are digital books better or worse than physical books? For gaming, a similar thing would be to ask if physical boxes are better or worse than digital copies, not if PC gaming is better or worse than tablet gaming. Choosing between two kinds of games - PC or tablet-based - can be likened to choosing between two kinds of books - say, ‘serious’ fiction or ‘light’ fiction - not between two kinds of medium. That's why your analogy doesn't work.
With gaming, there are also such considerations as PC interface vs. tablet interface and the way they influence what kinds of games are available on the PC and what on tablets, etc. However, if I read a book on mathematics or a piece of literary criticism, what changes if I read it in pdf compared to reading it as a physical copy? I often do both, and often switch between the two.
