It is sad that some are trying to downplay why it doesn't matter. If it didn't matter why are we still not playing in 480p? Some good points here, it is called progress. There is a reason 1080P is the mark people have been trying to hit for years. Not on you tube or cherry picked stills, on a decent 1080p display, the difference is very noticeable. Is it everything?? No, but it certainly matters. If I had a choice to play the same game in 720P or 1080p, I think any logical person would rather 1080p.
I come from a pc gaming background, resolution makes a big difference.
